Why does clip space in OpenGL have 4 dimensions?

WebI think the reason this exists is for easy comparisons. If the coordinates have been divided by the clip space dimension, then the coordinate that has 1 or more components with a value higher than 1, exists outside the clip space. So if your clip space is let's say 1024, but the coordinate is [2000,3,-100] then the x (2000) component is outside ... WebNormal textures.

Web8 de set. de 2007 · The clip-space rules are different for OpenGL and Direct3D and are built into the projection matrix for each respective API. As a result, if Cg programmers rely on the appropriate projection matrix for their choice of 3D programming interface, the distinction between the two clip-space definitions is not apparent. Web12 de jul. de 2009 · But clip space is defined differently in OpenGL and D3D. In OpenGL clip space Z is within [-Wclip, Wclip] while in D3D it is limited to [0, Wclip]. After the homogeneous division by W this results in normalized device coordinates (NDC) in the ranges [-1, 1] for OpenGL or [0, 1] for D3D, respecively.
