WebAug 19, 2015 · Textures stay very crisp and clean. (the example is DX10 and HLSL based, would take some time to port it to GLSL accurately) These techniques don't super-sample or multi-sample, so lines that appear less than 1 pixel in thickness will appear with gaps and not be anti-aliased correctly. This is the downside to using a non-MSAA approach. WebOct 14, 2024 · See GLSL version 4.60 (most recent) (from OpenGL Shading Language 4.60 Specification - 4.1.7. Opaque Types): When aggregated into arrays within a shader, these types can only be indexed with a dynamically uniform expression, or texture lookup will result in undefined values. In the GLSL version 330, the restriction is even harder. WebNov 18, 2005 · Currently it seems like the only way to achieve support for rectangular texturemapping in GLSL on both NVidia and ATI is to force textures to use GL_TEXTURE_2D, increasing the required size up to the nearest power-of-two size. If ARB_non_power_of_two is available, this is a fine solution and the textures dont need to … dachhaube remitop vista rauchglas
