vertex

vertex: string

The GLSL implementation of the vertex shader. Instead of main, it implements void effectMain(vec4 position) where position is the vertex position in normalized device coordinates ([-1..1]). effectMain should compute whatever information is required by the fragment shader. It should not assign to gl_Position.
