- shows the basic steps for a circle SDF
- extends this to show how to animate, combine and blend shapes
- the preprint from Ray Tracing Gems 2 covers two techniques for caustics
- One focuses on the caustics around metallic and transparent surfaces
- the second is for caustics cast by water surfaces
- the article presents the idea of compensating for shortcomings of an upsample technique in the downsampling step
- shows the development of an improved downsample filter to compensate for bilinear upsampling
- discusses how this is related to the typical sharpening of mipmaps done as part of game art pipelines
Threedy is a young Fraunhofer spin-off with a considerable number of high-profile customers in the german automotive sector.
We develop the Visual-Computing-as-a-Service platform instant3Dhub to enable our customers to leverage the true value of their 3D data in industrial applications – any data, any device, any size.
instant3Dhub has a strong focus on CAD data visualization, from browser-based to mixed reality applications and delivers out-of-the-box collaboration and augmented reality features.
We are looking for graphics programming enthusiasts to support our core development team for the 3D streaming with a focus on the evolution of our web frontend build on WebGL.
