3000th commit - IrrlichtBAW (GIT repo, v 0.3.0-gamma1)

[sodandk]

test of dry/wet. see at 3:00

blocks can be moist and will dry over time, and as we put rain in soon, then stuff get moisty
currently moist spreading can be seen around small lakes and ocean.

Roadmap for version 0.3:
1) Disable setShaderConstant and deal with uniform blocks just through uniform buffers (with suggested max buffer size of 16k, less than 12 blocks per shader stage and less than 24 in total)
2) stdint use throughout, u{8,16,32,64} and s{8,16,32,64} as well as c8 will be abandoned
3) SIMD matrix4x3 and matrix4 classes only
4) Counters of drawcall and other API calls
5) DrawIndirect (and MultiDrawIndirect)
6) Compute Shaders
7) Compute Shader LoD determination for all InstancedMeshSceneNodes at once (instead of 1 per 4 LoDs if ARB_transform_feedback3 or 1 at a time with ARB_transform_feedback2 only)

Version 0.4:
1) SIMD replacements for all 2D and 3D math classes
2) Corrected allocation and new/delete operators for all classes which use SIMD vectors etc.
3) custom std::allocator which allocates on 16,32,64 or 4096byte boundaries

[devsh]

Skipping Transform feedback the 3.3 GL core version and running straight ahead to ARB_transform_feedback2 because it seems to be a much more sane version of the functionality

So the engine support will be for Nvidia GeForce 200 series, Radeon HD 4000 series, and Intel HD Graphics bundled with Ivy Bridge CPUs and up

Hey you guys, I got IrrlichtBAW working with CMake not sure if that peaks anyone's interest in this thread. I do not have the link in my clipboard but it is in the same one I posted in earlier. Hopefully someone finds it helpful

[Virion]

Really good work!

[The_Glitch]

Hey Devsh can I uses hlsl with this it seems really great a lot of things that shader pipeline is missing?

[devsh]

GLSL only, OpenGL only, Vulkan when Android support will be incorporated.

We're holding back the release until we can implement Texture Buffer Objects and fix animated skinning to GPU-powered.

[christianclavet]

Great! You got examples in the repo! Somebody found a way to integrate a GUI with this?

[sodandk]

We did our own GUI system.... We might release the GUI system at some point.

[devsh]

Our GUI was written for old irrlicht, and fixed for our fork.

The ideal GUI could be drawn in one drawcall (trust me).

[sodandk]

Yup

[devsh]

GPU Skinning, Boning and Instancing of Skinned Meshes is coming

Hi devsh, tried compiling your irrlicht fork from the git repo and ran into a few issues using GCC 6.2.1 20160830 on Linux 4.7.4-1-ARCH x86_64

1) Compiling straight after cloning repo gave the following errors, looked SIMD related (not full output):

I'm guessing my gcc version is too recent for irr 1.8.3. Latest Irrlicht trunk revision compiles fine - I will try to look into this later.
