I started working on a new sky dome scene object today.  This scene object will be much better than the current sky box implementation that the engine uses.  It’s much easier to animate textures on a dome, as compared to a box … Continue reading →

I’ve been adding support for some new high dynamic range (HDR) pixel formats to the engine.  I added a 32-bit per-pixel integer format (A32B32G32R32) that can be used with OpenEXR images.  The image processing library in the engine can be used to … Continue reading →

I updated all of the external codec (compression/decompression) libraries that are used by the Orion Engine.  This includes: zlib, LibTIFF, libpng and OpenEXR.  I’m glad I updated them.  As it turns out, the old code that I was using had quite a few known … Continue reading →

The exporter can now export skinning information created using the Physique modifier in 3ds Max.  A hierarchy of bones and/or a biped can be used to animate the mesh.  Both rigid vertex and blended rigid vertex types are supported.  The data is … Continue reading →

I’m just about finished adding “DirectX Shader” material support to my 3ds Max exporter plug-in.  All of the effect parameters that you specify in the rollout will get exported with the subsets of a mesh.  I had to add new … Continue reading →

I’m still updating the 3ds Max mesh file exporter that I use with the engine.  I already had a feature to export per-vertex diffuse colors, but now I also have a feature to export per-vertex shading and/or illumination colors.  Many … Continue reading →

I updated the Orion Engine 3ds Max exporter plug-in to work with 3ds Max 2010 (R12).  There were some changes with how assets are enumerated, i.e. texture files, effect files, etc.  The latest changes were implemented as a conditional compilation, … Continue reading →
