I've … WebAug 25, 2014 · And this is the case with your cube - the cube in general has just 8 corners, but all of those corners connects 3 sides and every side has different normal, so it's the reason why all example cubes you've seen had 24 vertices. In fact your cube is very similar to a sphere, with very simple geometry, in a way that every vertex on the sphere has ... WebThe solution is the index buffer. In DirectX, an index is an int storing the number of a vertex. They are given in order, so the first vertex in a buffer is vertex number 0, the second is vertex number 1, the third is 2, and so on. And index buffer is a buffer in memory that stores the order in which vertices should be rendered. birmingham city korfball club

Sorted by: 2. For the index buffer you have used the array data type Uint16Array: var indices = new Uint16Array ( [...]); So you have to use enumerator constant gl.UNSIGNED_SHORT rather than gl.UNSIGNED_BYTE for the data type parameter: gl.drawElements (gl.TRIANGLES, indices.length, gl.UNSIGNED_BYTE, 0);
