Continuous Integration

We use TeamCity as a continuous integration server to build different configurations of Unigine engine, tools, SDKs and so on. We also use Trac as an issue tracker. The problem was lack of their native integration, but it's solved: Max wrote a TeamcityIntegration plugin, feel free to use it.

BTW, it takes about 5 minutes to make full rebuild of Unigine (engine+tools, both release and debug) on a Linux build node, while the Windows one (which has more powerful hardware) spends 12+ minutes for the same build type. So ccache rules, we do miss it for Visual Studio.

CUDA vs OpenCL vs SPU Part IV

Finally I've got radix sort implementation which is working on AMD OpenCL. This is a link on previous sorting algorithms test. And now we have new more interesting results :) Time of GPU sorting includes time of data downloading from video memory. Sorted structure is single uint2 array for bitonic sort, and two int arrays for radix sort.

BodyRope

This is a new physics object which can be used for cheap rope simulations.

Terrain occluder

WorldOccluderTerrain is a new node which can occlude all invisible objects in very efficient way. Heightmap image is used as data source and raycasting operations are performed on CPU. Cone step mapping is used as raycasting optimization. Artistic quality of raycasted image is ugly but number of occluded triangles is very large :)

Terrain editor

First version of terrian editor. There are some time lags by texture update because video is grabbed in real-time:

Light shafts

This is a new volume_shaft_base material on ObjectVolumeBox:

PlayStation3 Unigine status X

Each rendered triangle of static and skinned meshes is culled by view frustum and front/back face tests on SPU. Skinning is performed entirely on SPU with both ordinary and dual quaternion skinning modes available. Vertex buffers for particles are generated on SPU with view frustum culling. Particles can be sorted by depth on SPU. Particles are simulated on SPU with awesome performance.

PlayStation3 Unigine status IX

Heap of code for view frustum and back face SPU culling, but result is wonderful.
