Irrlicht Engine

How's that going by the way?

Just explode the model, it just requires a new transform for each submesh, the Irrlicht parent-child code does the same thing.

Hi, did this get fixed?

The D3D shader, bump shader, is in CD3DNormalMapRenderer.cpp then?

I guess these shader were written in asm... any good reference guides or tools to convert them to HLSL??

How about multiply the sub-mesh offset matrix by the original transform matrix, call SetTransform with that in the node's Render() proc, having passed the same offset matrix to the shader previously, and the following mesh or node render, reset the matrix... that should work, right? The GPU will sim...

Anyone knows how to offset the position of sub-meshes?

I'd like to explode something by manipulating the position and rotation of the submeshes.

Okay, sounds good! Where the hell are those pesky irrlich shaders stored? I'll convert them, I think they are in asm, to HLSL if any one can tell me where they are hard coded? :) In particular, the bump map shader, and the metal one. Once they're working in HSLS, it will be easy to add them for bGFX...

Okay, so create n threads to process node animation (pos change), and rendering preparation up to the actual rendering point, then render the lot in the main thread, doesn't sound too difficult, is that what you mean? I don't know how much overhead bGFX would have, but I guess to get the most out of...

Have you look at or tested the Irrlicht bGFX addition, seems like the way to go to support all drivers, as long as its efficient.

I guess your Vulkan driver will be fast and easy to expand though, without all the other stuff needed for something like bGFX:

Why bother now that bFGX has been patched in, isn't that the way to go?

Also it supports the SPIRV language for shaders and GPU compute.

Only that the DX9 driver works so well, and fast. Is there any guarantee that the bGFX driver would be as fast and fully compatible, with all the same shaders working? In regards to shaders, the GLSLC tool looks great, converting HLSL and GLSL to SPIRV. It would be useful if the HLSL/GLSL source cou...

The calls to load the shaders (2 or 3 of them), failed, I thought it was the AMD shader compiler not happy with the syntax. I've seen this many times where shader code compiles on the NVidia but not on the AMD, usually the code needs minor adjustment. I´ll take a look at it again soon and try to fix...

@AReichl - any pointers on the necessary patches would be a great help!

Which branch of Irrlicht does the patch work with?

I have your code running, Irrlicht + BGFX, but there are problems with the first and some other shaders, probably because I'm using a different GPU to those tested on. Sometimes NVidia code runs the shaders, and AMD fails, or the other way around. As the shaders are coded into the code files, its no...

Okay, any idea of the improvement of Bgfx compared to DX9?

I'd love to tun a benchmark, so any help would be appreciated
