[simavr] / examples / board_reprap / gfx / scene.vs

// Used for shadow lookup
uniform mat4 shadowMatrix;
varying vec4 ShadowCoord;
varying vec2 texCoord;
   
void main()
{
        ShadowCoord= shadowMatrix * gl_Vertex;

        gl_Position = ftransform();
    gl_TexCoord[0] = gl_MultiTexCoord0;
        gl_FrontColor = gl_Color;
        texCoord = gl_MultiTexCoord0.xy;
}
