Detailed Description
A Buffer can be used to create intermediate buffers to share data between render passes in an Effect.
Note: If the name property of the Buffer is empty, it will reference the default output texture of the render pass.
Property Documentation
bufferFlags : enumeration
Specifies the buffer allocation flags. The default is Buffer.None.
| Constant | Description |
|---|---|
| Buffer.None | No special behavior. |
| Buffer.SceneLifetime | The buffer is allocated for the whole lifetime of the scene. |
Specifies the texture format. The default value is Buffer.RGBA8.
| Constant | Value |
|---|---|
| Buffer.RGBA8 | |
| Buffer.RGBA16F | |
| Buffer.RGBA32F | |
| Buffer.R8 | |
| Buffer.R16 | |
| Buffer.R16F | |
| Buffer.R32F |
Specifies the name of the buffer.
Note: When this property is empty, the Buffer will refer to the default output texture of the render pass instead of allocating a buffer. This can be useful to override certain settings of the output, such as the texture format, without introducing a new, separate intermediate texture.
Specifies the size multiplier of the buffer. For instance, a value of 1.0 creates a buffer with the same size as the effect's input texture while 0.5 creates buffer where both width and height is half as big. The default value is 1.0.
textureCoordOperation : enumeration
Specifies the behavior for texture coordinates when sampling outside the [0, 1] range. The default is Buffer.ClampToEdge.
| Constant | Description |
|---|---|
| Buffer.ClampToEdge | Clamp coordinates to the edges. |
| Buffer.Repeat | Wrap the coordinates at the edges to tile the texture. |
| Buffer.MirroredRepeat | Wrap the coordinate at the edges, but mirror the texture when tiling it. |
textureFilterOperation : enumeration
Specifies the texture filtering mode when sampling the contents of the Buffer. The default value is Buffer.Linear.
| Constant | Description |
|---|---|
| Buffer.Nearest | Use nearest-neighbor filtering. |
| Buffer.Linear | Use linear filtering. |
