About

dexvt-test is a c++/glsl/glm-based 3d engine. It features environment-mapped reflection/refraction/double refraction (with Fresnel effect, chromatic dispersion, and Beer's law), screen space ambient occlusion, bump mapping, Phong shading, Bloom filter, 3ds mesh import, 3D Inverse Kinematics (Cyclic Coordinate Descent), and platonic primitives generation. Platonic primitives supported include sphere, cube, cylinder, cone, grid, tetrahedron, and round brilliant diamond.

See sister project demonstrating IK features: dexvt-lite
