Finally I implement a full HDR rendering pipeline with my own engine JH3D (3D game engine for Adobe Flash 11+). Of cause there is no floating texture at the moment. I used logLuv pack for out putting. For log luminance, I used 2 channels for packing luminance value and 1 channel for stroring the sign. Finnaly, compiled the whole scene with human eye adaption and Uncharted 2 tone mapping operator.
The main features of this demo are:
- HDR pipeline ( luminance adaption, exposure adjust, bloom, contrast adjust, color balance, saturation adjust, gamma correction)
- Cascaded shadow mapping with PCF filtering
- Procedural vegetation animation.
- Pre-GPU-based light map baking( sky light, shadow map, AO, hdr format(LogLuv packed)).
