We often need to pass arrays of specific types for functions such as glBufferData. type TVec2f = record x, y: GLfloat; end; type TVec2b = record x, y: GLubyte; end; var verts: array[0..2] of TVec2f; begin glBufferData(GL_ARRAY_BUFFER, sizeof(TVec2f) * 3, @verts, GL_STATIC_DRAW); // pass an array of TVec2 but how does JS know this?Here is an JS example: ---JS-START--- var vertices = [-0.5, 0.5, -0.5, -0.5, 0.0, -0.5,]; // Create a new buffer object var vertex_buffer = gl.createBuffer(); // Bind an empty array buffer to it gl.bindBuffer(gl.ARRAY_BUFFER, vertex_buffer); // Pass the vertices data to the buffer gl.bufferData(gl.ARRAY_BUFFER, new Float32Array(vertices), gl.STATIC_DRAW);
So it does exist :) Nice, I should have typed gl.bufferData instead of glbufferdata when searching :-) Michael. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
