The Line Integral Convolution (LIC) is a vector field visualization technique that involves convolving noise with a vector field. This produces streaking patterns along the … Read More

Introduction The Physically Based Rendering shader in VTK has recently been improved with the addition of an anisotropy and a clear coat model. We are … Read More

Introduction In our last step on the Physically Based Rendering Journey with VTK, we introduced an anisotropy model to simulate materials that exhibit different reflecting … Read More

Introduction In our previous post on the new features of the PBR shading in VTK 9.0, we introduced the HDR environment and how to use … Read More

Introduction Last year we introduced the beginning of Physically Based Rendering in VTK. Now the journey to modern rendering in VTK continues with new features … Read More

Introduction Particle-based fluid simulations are very popular in computer graphics. For coolant flow, engine analysis, blood flow, and interactive applications, particle-based simulation methods are often … Read More

Introduction Until VTK 8.2, surface shading through the vtkPolyDataMapper is computed using the Phong reflectance model. While it achieves plausible results, it requires the user … Read More
