ScreenSpaceEffectSource Interface
The GLSL implementation of the effect produced by a ScreenSpaceEffectBuilder, to be integrated into a complete shader program. The effect shader code differs slightly from that of an ordinary shader:
- Instead of
main, it should implementeffectMain.- It can include other functions, variables, etc outside of
effectMain.
- It can include other functions, variables, etc outside of
- It should omit declarations of uniform and varying variables - these will be generated from those supplied to ScreenSpaceEffectBuilder.addUniform and ScreenSpaceEffectBuilder.addVarying.
The program receives one pre-defined
uniform sampler2D u_diffuserepresenting the viewport's rendered image.
Properties
| Name | Type | Description | |
|---|---|---|---|
| fragment | string | The GLSL implementation of the fragment shader. | |
| sampleSourcePixel | undefined | string | If the fragment shader shifts pixels from their original locations, then by default element locate will not work, because it expects the pixels produced by an element | |
| vertex | string | The GLSL implementation of the vertex shader. |
