This means that as light intensity increases the surface will get brighter in a non linear way.
When they are used in a shader the colors of high luminance are actually brighter then they should be for linear lighting. When you are using gamma rendering, the colors and textures that are supplied to a shader have a gamma correction applied to them. This more correctly models lighting intensity falloff on surfaces. Secondly lighting edges will also be harsher. Firstly when rendering in linear mode, the additional gamma correction that is performed will make a light’s radius appear larger. The falloff from distance- and normal-based lighting is changed in two ways. lights striking surfaces will have a different response curve and image effects will behave differently than in the gamma pipeline. When using linear rendering, input values to the shader equations are different than in gamma space. Differences Between Linear and Gamma Rendering When writing the resulting value to the framebuffer, it will either be gamma corrected or left in linear space for later gamma correction this depends on the current rendering configuration. These inputs are then supplied to the shader and lighting occurs as it normally would. Textures are sampled using hardware sRGB reads the source texture is supplied in gamma space and then on sampling in the graphics hardware the result is converted automatically. For colors this conversion is applied implicitly if you are in linear space. If linear rendering is enabled then inputs to the shader program are supplied with the gamma correction removed from them. Much of the time this looks acceptable as the two wrongs go some way to cancelling each other out. Albeit these values being in gamma space, all shader calculations treat their input as if it was in linear space, and additionally, when writing the shader outputs to memory, no gamma correction is applied to the final pixel. In the gamma rendering pipeline all colors and textures are sampled in gamma space, ie, gamma correction is not removed from images or colors before they are used in a shader. Linear rendering ensures that both inputs and outputs of a shader are in the correct color space which results in a more correct outcome. lighting and image effect it will lead to slightly wrong results as the equations are calculated in a non-linear space.
If these textures are used in the usual equations for e.g. Normally textures exist with gamma correction pre-applied to them, which means that when the textures are sampled in a material the values are not linear. “flickering” highlight artifacts (1) 3D (44) 3d architectural visualisation models (12) 3d article (1) 3d artist magazine (1) 3D image rendering (11) 3d images (29) 3d magazine (1) 3d models (1) 3d people (3) 3D photo render (5) 3D Photorealistic Rendering (4) 3d realism practical and easy workflows (1) 3d rendering (10) 3D renders (4) 3D total publishing (1) 3D Tutorials (18) 3d visualizer (1) 3Ds Max (67) 3ds max Autodesk Renders (7) 3dsmax (5) AdvArray (1) Aerial Shot settings (1) AMD graphics cards (1) and 3ds Max (1) animations (1) ar (1) article (1) AutoCAD Drawings (2) autodesk (28) Autodesk Renders (1) automodeller (1) automotive (2) backburner (1) background photo post-production (1) BatchCameraRender (1) best vray materials (2) best vray tutorials (2) bsp (1) BSP tree (1) camera (1) caption (1) CG Society: mental ray 3.Linear rendering refers to the process of rendering a scene with all inputs being linear.
