摘要: Assume a parametric curve can be denoted by P(t), any attribute T can be interpolated linearly with:T = (1 - t) * T0 + t * T1 (1)T0 is the attribute at t=0, and T1 is the attribute at t=1.Differentiate equation (1) we have:dTdx = (T1 - T0) * dtdx (2)Now the problem turns into how to compute dtdx.Usi 阅读全文

摘要: For triangles, as well as other planar shapes, there's an affine mapping from parametric space to object space, said M.In parametric space, we know the parametric coordiantes for 3 triangle corners are (u0, v0), (u1, v1), (u2, v2) respectively.While in object space, the 3D coordinates for 3 tria 阅读全文

摘要: 1. Processing each l-th primitive at the binning step, where l=log10(N) and N is number of primitives in the current node.2. Experiments demonstrated that it is beneficial to switch to exact SAH computation when the number of primitives in the current node is less or equal to the number of bins.3. E 阅读全文

摘要: Here are some tips:1. Convert all VC projects to ICL projects by Use Intel C++.2. SetStructure Alignmentto 1 byte or 4 byte, otherwise ICL may default to 16 byte.3. If you don't want to have dependency on libmmd.dll, use Multi-threaded rather than Multi-threaded DLL to static link with ICL runti 阅读全文
