Edit documentationA shared texture slot: a texture that shaders find by name. See X3DSharedData for registration, filtering,
register and BindLocation.
When the client creates the slot, it also creates a 1x1 default texture of the
dimension that type selects, filled with DefaultValue. Slots with the same type,
DefaultValue and TextureElementType share one default texture.
Properties
DefaultValue
Vec4 = [0, 0, 0, 0] 15.21
The colour of the default texture, (r, g, b, a).
ElementCount
U8 = 4 15.5
Purpose not yet identified. The client does not read it when it creates the slot.
IsCurrentFramebufferDepthRead
Bool = false The client stores it with the texture slot. What it changes is not yet identified.
PlatformMask
U32 = 0 The platforms on which the slot loads, see X3DSharedData.
The shared sampler that the client stores with the texture, found by the linked sampler's name. If PlatformMask or ShaderModel filter that sampler out, the texture has no sampler.
ShaderModel
U8 = 0 14.23
The renderer mode in which the slot loads, see X3DSharedData.
TextureElementType
U8 = 0 15.5
Selects the pixel format of the default texture: 1 and 2 give one format, any other value another. Which formats these are is not yet identified.
frequency
U8 = 0 Purpose not yet identified. The client does not read it when it creates the slot.
name
String = "" The name under which shaders find the texture. Before the lookup, the client strips the suffix _SharedTexture or __TX from the name that the shader declares.
register
I32 = -1 If -1, the client binds the texture per effect. Any other value leaves it out of the effect bindings. See X3DSharedData.
type
U8 = 0 The dimension of the default texture:
| Value | Default texture |
|---|---|
0 |
2D |
1 |
3D |
2 |
Cube map |
3 |
2D. Shipped data uses it for the shadow map depth texture. |
4 |
Cube map. Shipped data uses it for the point-light shadow map depth texture. |
5 |
2D array |
6 |
2D array |
7 |
Cube map array |
8 |
Cube map array |
A value above 8 creates no default texture. What distinguishes the values of each
pair is not yet identified.
