| vec4 OivBackColor | ( | in int | index | ) |
Get the back color of the input vertex or fragment at index.
Available in: Tessellation Control Shader Tessellation Evaluation Shader Geometry Shader The equivalent legacy value is gl_in[index].gl_BackColor
| float OivFogFragCoord | ( | in int | index | ) |
Get the fog frag coord of the input vertex at index.
Available in: Tessellation Control Shader Tessellation Evaluation Shader Geometry Shader The equivalent legacy value is gl_in[index].gl_FogFragCoord
| float OivFogFragCoord | ( | ) |
Get the fog frag coord of the input vertex or fragment.
Available in: Vertex Shader Fragment Shader The equivalent legacy values are: Vertex Shader: gl_FogCoord Fragment Shader: gl_FogFragCoord
| vec4 OivFragmentColor | ( | ) |
IN.
Get the interpolated color for this fragment (as defined by OivSetFrontColor and OivSetBackColor in previous stages). Available in: Fragment Shader The equivalent legacy value is gl_Color
| void OivFragmentOutput | ( | in vec4 | outputValue | ) |
Set the output value of the current fragment.
This is a convenient function that calls OivFragmentOutput(0, outputValue) Available in: Fragment Shader The equivalent legacy call is: gl_FragColor = outputValue;
| void OivFragmentOutput | ( | in int | bufferIndex, | |
| in vec4 | outputValue | |||
| ) |
Set the output value of the current fragment in the buffer specified by bufferIndex.
Available in: Fragment Shader The equivalent legacy call is: gl_FragData[bufferIndex] = outputValue;
| vec4 OivFragmentTexCoord | ( | in int | unit | ) |
Get the interpolated texture coordinates for this fragment.
Available in: Fragment Shader The equivalent legacy value is gl_TexCoord[unit]

Get the front color of the input vertex or fragment at index.
Available in: Tessellation Control Shader Tessellation Evaluation Shader Geometry Shader The equivalent legacy value is gl_in[index].gl_FrontColor
| void OivInitVertexData | ( | ) |
OUT.
Some GPU require vertex data to be initialized even if you don't use them. If you encounter message error such as: "The fragment shader uses varying _I;OIV_VERTEX_DATA;xxx, but previous shader does not write to it.", you should call this method at the beginning of your vertex shader main.
