Hello Forum,

i am trying to follow a tutorial about shaders and it says something about the model position of a pixel with a varying vector. the code used is: varying vec3 vPosition; void main() { vPosition = position; gl_Position = projectionMatrix * modelViewMatrix * vec4( position, 1.0 ); } this gives me errors in the shader and it doesnt compile... i am sorry i am really a noob about those things. what is the right approach within jitter? thanks for your help
