Indigo 4 Lets You Have Full Graphics Rendering Over OpenCL

Many have hypothesized in the past about implementing full OpenGL for graphics over OpenCL -- or now, implementing OpenGL directly over Vulkan -- while Glare Technologies with their Indigo renderer appears to be one of the first renderers to achieve 100% GPU rendering over OpenCL.

Indigo 4 has been in public beta since April but I only heard about this work this morning when one of their developers contacted me via e-mail. Up to now, I hadn't heard of Indigo. They describe Indigo as "an unbiased, physically based and photorealistic renderer which simulates the physics of light to achieve near-perfect image realism. With an advanced physical camera model, a super-realistic materials system and the ability to simulate complex lighting situations through Metropolis Light Transport, Indigo Renderer is capable of producing the highest levels of realism demanded by architectural and product visualization."

With the Indigo 4 renderer in its beta state, "we are using OpenCL to deliver 100% pure GPU rendering, which means very fast rendering on all OpenCL compliant GPUs, including AMD, Intel and Nvidia GPUs."

Indigo also supports NVIDIA's CUDA in addition to OpenCL.

The company provided this as one of the examples of Indigo 4 GPU rendering with OpenCL without any post-processing effects... Nice!
