View Full Version : GPU rendering and computing for Lightwave?

It's relatively long time that hardware acceleration is available in some software packages.
What's the status of lightwave for this? What's for GPU rendering or calculations?

"NewTek is closely monitoring GPU rendering, their VPR is a fast mutli-threading solution. Mark Granger has worked very closely with Nividia and the original CUDA beta – but he feels that perhaps the price of going down the GPU approach may not be worth it. “The cost of supporting GPU rendering in terms of what we would have to give up in terms of flexibility are so extreme – I dont think it is worth it to us"

I haven't completely get this sentence. Is newtek interested in GPU approach or not?

Skiddish or not, they had best start moving that way. Just 4-5 years ago, even in the 3ds Max community, many scoffed at the need for Interactive Rendering, ala FPrime. It has since been all the rage, and most rendering solutions have some version of it. Then they scoffed at GPU renderers...period. Not enough memory on the cards....too hard to write for....blah,blah, blah. Well those excuses are falling by the wayside now that you have a flurry of competing rendering solutions that offer either full or partial GPU rendering capability. Octane, Thea, Arion (formerly Fry Render), Furryball, Cycles, etc. If they haven't even started down this road yet, they are going to find themselves way behind the power curve, soon.

This isn't just a fad. The CPU arms race is over. AMD publicly bowed out of the high end CPU segment a few years ago. Intel has since stagnated the pace of performance enhancements with every generation and is more concerned with power efficiency and offering some GPU capability on the die/chip. However, the GPU arms race is alive and well, and FOR THAT REASON ALONE, LW3DG had better get off the john and get some GPU-based development started.

There is no reason there cannot be a classic render and a separate GPU mode. Mental Ray and iRay are a good example of this, in 3ds Max. There are indeed some limitations in iRay, but in many circumstances it can be just what the doctor ordered.

Octane support LW. I think LW have more important stuff to work on to get back clients. Better keyframing, drag and drop interface (Im dreaming), Better deformers in Layout, Some kind of Mograph module, Stuff that will appeal to beginners and motion designers. Spline control is a good start though...

Agreed, Taro,
Let those guys that are doing them already be the pioneers for this.

Octane is great; Arnold is on the way. We aren't too bad off, gpu-wise, already.
