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. WebOpenGL-like: The clip space depth goes from –1.0 at the near plane to +1.0 at the far plane. This applies to OpenGL and OpenGL ES. Also note: from within the shader you can use the UNITY_NEAR_CLIP_VALUE built-in macro to get the near plane value based on the platform. Comment. Bunny83 ModLunar MaxGuernseyIII

This is commonly referred to as the viewing transformation. WebSo if your clip space is let's say 1024, but the coordinate is [2000,3,-100] then the x (2000) component is outside the clip space (which only ranges from -1024 to 1024). …
