Woodworked furniture renders by Headroom

Written Friday 30 Mar

Indigo user Headroom has been using Indigo to create wonderful renders of woodworked furniture.

The first render is a chair design by David Haig. Read the forum thread here.

Indigo Material Editing Videos

Written Monday 26 Mar

Recently we've been revamping our documentation and tutorials for the release of Indigo 3.2 Stable, which will be released in the coming weeks. As part of this effort we've produced 3 videos illustrating the basics of material editing in Indigo, which you can find on YouTube:

Part 1: Diffuse, Phong and Oren-Nayar
Part 2: Specular, Glossy Transparent and Diffuse Transmitter
Part 3: Texture channels

These short videos are hopefully informative and to-the-point, and we expect to release more videos covering the installation of various exporters soon.


 

Sarah Dorweiler Visualisations

Written Monday 27 Feb

Sarah Dorweiler at Sarah Dorweiler Visualisierungen (Visualisations) has been creating some truly amazing architectural and interior visualisations with Indigo Renderer.

Sarah has achieved a remarkable combination of complete photorealism and style in her images, as is evident from her gallery.

Plexiglass Palace

Written Friday 24 Feb

A collaborative work between myself (lycium) and Pasternak on deviantArt, this scene was modelled using Structure Synth and rendered with Indigo Renderer.

Gritty black & white render, "Decay" by Enslaver

Written Thursday 9 Feb

Well-known for his highly enjoyable abstract works, Indigo forum user Enslaver has knocked another one out of the park with his Daz3D modelled + ivy covered composition "Decay." Currently there's a whole page of compliments in the Simple Renders thread just for this one image!

Produced with the new IndigoMax exporter for 3ds Max, with 60 million polygons worth of ivy, it's a great showcase for what can be done with Indigo's camera controls.

Announcing IndigoMax

Written Tuesday 31 Jan

In case you missed the announcement on our 3ds Max forum, we have a brand new 3ds Max exporter in development: IndigoMax!

Through a partnership with Jakub Jeziorski, a fully native plugin for 3ds Max using the Indigo SDK is being developed to take integration with Indigo to the next level. Early releases are available from our forum here: http://www.indigorenderer.com/forum/viewtopic.php?f=9&t=11368

Welcome on board, Jakub!

A simple and fun render with the new exporter has been made by ENSLAVER (click to enlarge):




 

Recent progress in the CUDA ecosystem

Written Friday 16 Dec

Less than a week after my previous post about how "only OpenCL can expose massively parallel compute capabilities in a vendor-neutral way", NVIDIA open-sourced their CUDA compiler! Obviously they are intently watching this blog, and had to react to my nay-saying.

Jokes aside, this is a big move for CUDA as it allows anyone with the ability to create LLVM ASTs from their scripting language to use the PTX backend. Indigo already features a dynamically-compiled scripting language, Winter, and this technology could be extended to output optimised code for NVIDIA GPUs directly. Of course, this isn't necessarily an approach we'll use, however it illustrates the potential of having a powerful optimising compiler for many platforms behind your domain-specific language.

It will be exciting to see how this develops, as more back- and front-ends are added to the burgeoning LLVM framework.


 

Recent progress in the OpenCL ecosystem

Written Friday 9 Dec

Recently AMD announced an increased focus on its Accelerated Parallel Processing SDK, promising more frequent updates tied to display driver releases on all platforms; AMD Product Manager for Compute Solutions Mark Ireton wrote on their developer blog, "[...] we will also be upgrading our OpenCL solution on a more frequent basis through the regular monthly Catalyst driver updates."

NVIDIA, for their part, are continually improving their OpenCL implementation with each driver update, approaching the performance of its native CUDA language. Much as I love the lean and mean CUDA 4 API, only OpenCL can expose massively parallel compute capabilities in a vendor-neutral way (and it's nice to be able to JIT from source), so in the long term I expect OpenCL to become the de facto standard for parallel computation.

AMD and Intel already have an OpenCL SDK which supports their CPUs, and this is important since they already include (or soon will) considerable GPU-like parallel compute resources. The tight integration of these heterogeneous compute resources is quite unlike the present norm, in which discrete cards with dedicated memory are connected to the CPU by a long PCI Express trip, and this will be an interesting scenario to optimise for in the future. Intel's Many Integrated Core (MIC) architecture is another one to watch in the future: with a widened x86 architecture (easy to program) and their manufacturing process leadership, we could see a compelling compute platform.

When we started developing for GPUs, we'd have to manually write out debug info to be returned to the host; unsuccessful runs were often met with a hard reset or blue screen. This is in stark contrast to the fantastic development tools we have now, including the ability to print out debug info from kernels, and do live debugging in Visual Studio - and it almost never hangs the machine. Two thumbs up!

It's clear that a great OpenCL implementation is important for these companies, and we are very pleased with the progress that is being made.


 

A bit more on UI improvements

Written Thursday 27 Oct

As you may already know, we improved the material and medium editing user interface for the upcoming Indigo 3.2 release.

Another important change to this is the way materials and media are linked to each other. In Indigo 3.0, the link ui was just a simple dropdown, which worked, but was far from ideal, since you had to search through long lists of material names.

This is how it looked in 3.0:

In 3.2, it looks like this:

We made a nice custom control for that, which offers convenient ways to link/unlink nodes:

- It functions as a search box. Just type the material name and select from a list of results matching your search query.

- It supports drag and drop from the scene graph

- Materials/Media can easily be unlinked by clicking the 'x'

- It also now checks if linking a material would create a circular material and does not let you do it

And by clicking the button with the arrow on it, it opens the material/medium/other node type linked for editing.


 

Indigo Shader Language and Winter talk

Written Sunday 23 Oct

I gave a lightning talk (10 min talk) on Indigo Shader Language (ISL) and Winter, at the European LLVM User Group Meeting in London, on the 16th of September.

You can view the talk slides in PDF form here.
