WebStride and offset are specified in bytes. You are using an interleaved vertex array with position and color both as 4 floats. To get from th i-th element in a particular attribute array to the next one, there is the distance of 8 floats, so stride should be 8*sizeof (GLfloat). WebThe offset uniform is supplied in the display function float fXOffset = 0.0f, fYOffset = 0.0f; ComputePositionOffsets (fXOffset, fYOffset); glUniform2f (offsetLocation, fXOffset, fYOffset); and the position was updated identically in the shader: vec4 totalOffset = vec4 (offset.x, offset.y, 0.0, 0.0); gl_Position = position + totalOffset; phillips 66 ev
