Color that models the specular reflectance of the material, and it has a shininess parameter a floatwhich models the size and intensity of the specular highlight. Regarding the specular map, in MeshPhongMaterialthis map is a grayscale map that further modulates 1 the intensity of the specular highlight, and 2 the reflectivity parameter used in environment mapping.
So, what does gloss map and specular map mean to you? Can you link to a live example?
An overview of materials in three.js
Can you give an example in which MeshPhongMaterial is deficient? My knowledge about game shaders is from Marmoset Toolbag. I build my meshes and present it there. There is also something like sketchfab. Anisotropy with map would be also wellcome : With that would be possible present more realistic models I think.
I would like to use three.Psl lumber
Wasn't aware of speculaMap with color, neither of glossMap. Gloss maps would be really helpful. I think you can give the specularMap a color tone by setting the specular color attribute of the phong material. If I understand it correctly the gloss map defines coefficients for the shininess of the material. Happy to implement this. I will file a PR in a few days to support roughness.
A model with a roughnessMap and metalnessMap would be appreciated. This now comes built in in MeshStandardMaterial.In three. There are also additional materials for rendering lines, points, shadows, and sprites. This post will serve as a general overview of materials in general in three.
I will give a very basic overview of the base Material class, and get into some of the differences between materials used with a Mesh. I will of course not be getting into every key little detail with each of theme, Some of these will deserve a full post explaining them in further detail. This is not my getting started post on three. This is an advanced post on three. Older posts on three. In most of these posts I have been sticking to three. All materials inherit from the Material base class.
This base class contains a lot of properties some of which are superseded by prosperities in a certain material. I will not be getting into the Base class in detail here, as I still need to write more demos with many of the properties.
Also This post is going to be pretty lengthly to begin with anyway. However I think I should at least cover some of the most important properties to be aware of in the base material class that I have dealt with thus far. When dealing with a material that will be used on a mesh in which faces will be viewed from both sides, the side property of the material base class may be of interest.
As you might guess this will make it so the material is used on both sides of the faces used in a mesh. BackSide constant as well. These two properties have to do with the opacity of the material. The transparent property expects a boolean value, which will turn transparency on or off depending on the value. If it is set true, and you do not see any opacity effect it could be because the default value for material.
Set the opacity property to a value between 0 and 1 to set the opacity of the material of transparency is enabled. This comes in handy when I just want to quickly add some solid color to a mesh, or do something involving just a color map. This is another basic material that is not used for anything advanced involving a light source, and shadows. The depth material can be used to show some depth to a mesh, rather than just having a solid color painted on each face.
Depth is based off the near, and far plane of the camera. White areas indicate that an area of the mesh is closer to the camera, while darker areas indicate that the area of the mesh is farther away.

This approach differs from older approaches in that instead of using approximations for the way in which light interacts with a surface, a physically correct model is used. The idea is that, instead of tweaking materials to look good under specific lighting, a material can be created that will react 'correctly' under all lighting scenarios.
In practice this gives a more accurate and realistic looking result than the [page:MeshLambertMaterial] or [page:MeshPhongMaterial], at the cost of being somewhat more computationally expensive. This calculates shading per pixel i. Note that for best results you should always specify an [page:.Wiring diagram car horn relay diagram base website horn relay
Technical details of the approach used in three. Any property of the material including any property inherited from [page:Material] can be passed in here. The alpha map is a grayscale texture that controls the opacity across the surface black: fully transparent; white: fully opaque.
Default is null. Only the color of the texture is used, ignoring the alpha channel if one exists. The red channel of this texture is used as the ambient occlusion map. The aoMap requires a second set of UVs. The texture to create a bump map.
The black and white values map to the perceived depth in relation to the lights. Bump doesn't actually affect the geometry of the object, only the lighting. If a normal map is defined this will be ignored. The displacement map affects the position of the mesh's vertices. Unlike other maps which only affect the light and shade of the material the displaced vertices can cast shadows, block other objects, and otherwise act as real geometry.
The displacement texture is an image where the value of each pixel white being the highest is mapped against, and repositions, the vertices of the mesh.
How much the displacement map affects the mesh where black is no displacement, and white is maximum displacement.Materials determine how the surface of our geometry is drawn in Three. If the Geometry is our skeleton, defining the shape, then the Material is our skin.
There are a variety of different types of materials in Three. The most basic material is the MeshBasicMaterial. You can pass a color in as a parameter to get a solid colored object, which has no shading. You can also adjust the opacity by passing in the opacity as a parameter with a value from 0 to 1 and setting transparent to true.
Another material we have is MeshNormalMaterial. This colors the faces of the mesh differently based on the face's normal or what direction they are facing. For allowing our material to respond to lights MeshLambertMaterial will give our geometry shading with a dull surface. Lambert is a common material in most 3D applications.

Just like before we can adjust the color. It also has an emissive property which adds a glow like color to the material. Similar to Lambert MeshPhongMaterial responds to lights but adds a metallic luster to the surface, reflecting light with more intensity.
You can also add a specular color and adjust the shininess property of this material to adjust the intensity of the light reflection. MeshStandardMaterial aims to combine Lambert and Phong into a single material. It has properties for roughness and metalness and adjusting these can create both dull or metallic looking surfaces.
A different kind of material is MeshDepthMaterial which draws the meshes grayscale from black to white based on the depth of the content. All of the materials we have discussed so far are mesh materials because they are applied to meshes. However there are other kinds of geometric objects within Three.
To draw a Line we must utilize LineBasicMaterial.Learning medina80sc.pw 04 :: Textures, Normal, and Bump Maps
This works similarly to MeshBasicMaterial. For dashed lines to work however you need to call a method on your geometry called computeLineDistances which uses the distance of the line to draw the dashes the correct size. Similar to drawing a LinePoints require the use of PointsMaterial.

Another special kind of material is SpriteMaterialwhich can take a texture map and be applied to a Sprite. Sprite's are a special kind of plane that are always facing the camera. Materials and their parameters combined with lights add a lot to the look and feel of 3D content.
Playing around with these alone can create some amazing visuals.

You don't know how long I've tried to get materials to look that good! That glass refraction is exactly what I needed. I couldn't resist making a couple of new ones. I've twitted it. This is sexy! I can't wait to use them!!!! You guys rock. Wingnut If you had not checked this you have to, this is awesome!
Hey, thanks for the lead, A. I was typing a PM So, here I am, and HI! It would be fun to darken that scene, turn-on a single candle with the new pointLight shadows feature Plus, the shadows will flicker with the candle, too. Deltakosh I'm trying to use PBR materials in my current project, I downloaded the latest code yesterday, but it says.
I copy pasted the code from the demo playground scene and didn't change anything except the textures path I named the folder as "images" instead of "textures".
Hi guys. Here's a super-complete zip of the package but with non -min version of pbrMaterial. All JS is included. It is glass and wood only, no plastic or metal. One way I learn about the tweek-able "knobs" of a new system its properties Index03 is my early steps at that. I animated glass. As almost always, the dynamicText ure is wide and squatty. Verdana is not the best font to use for dynamicText.
I side-tracked to fix the text readouts, and haven't returned to playing with the pbr and hdr yet. But, an indexOfRefraction range sweeper is active in index Grab this zip As for looking around the web for other.
If someone has links or knowledge about different. That is IF we are in an appropriate thread for pointing or talking. I'm all paranoid about where I post, these days. We don't have a " talk about anything you damned well feel like talking about " forum category. Friggin' programmers and their tendency to "box" everything. They sure cramp the style of we rubbery liquidy analog type. Quick-tests were having problems getting the glass to go transparent.
I could not see the wood through the glass. Again, though, I didn't spend much time experimenting, yet.

However, I would like to add to this object a bump map so that the reflection isn't so smooth.
What I want to do is use a small square JPG of white noise to make the aluminum have a "grain" to it so that has more of a reflective brushed metal look. However, this example uses a lot more than just a bump map, and all efforts to use that code and simple replace the files used for the bump mapping with my white noise JPG cause the texture to be completely invisible.
I can't, for the life of me, find a simple example of a brushed reflective metal texture anywhere You may get some interesting metal look with normal maps but it's not going to look much like brushed metal:. For brushed metal look you would need anisotropic shader. Something like rdad did here:. Also, for normal map shader you'll need to convert first your grayscale heighmap into blueish normal map, either:.
I used those links to generate a true normal map image, and have modified the simple floating cube example to use a ShaderMaterial for each face of the cube with the normal map that I generated. As far as I can tell, everything is set up according to how it is in the examples, yet I can't get the cube to show up. The same thing happens when I try to apply the material to the actual models I'm using, so I decided to go to a stupid-simple example and apply the ShaderMaterial there.
I know it is something incredibly stupid, but I've been banging my head against my desk for a few days now trying to figure this out. I have a legit normal map now, so that can't be it. It came down to using the command cube. I did notice, however, that the normal map doesn't actually modify the geometry at all. That normal map make actually adds bits that actually extrude from the model, whereas my cube is still perfectly smooth with the illusion of bumps.

It seems ok for me, I can see the cube and it appears to have some sort of normal map.Bunnings lathe chuck
Maybe there is some problem with your GPU? I went on to the three. Is there any way to get the same effect with my cube example?
