A few Questions

Hi Carsten I was just wondering, when will we see proper lighting on terrains?
Also on the Devmaster.net website, the Spherical Harmonic lighting is still listed, whats going on with it, is it still in the engine?


Thanks

Dear Scott,

your questions are good ones:

The implementation of shadow-maps (in this case as cascaded shadow maps), is one of my next major goals. I realize that the lighting of terrains is currently quite boring and that the Radiosity computations are slow, so this is a big issue to me that I'll address soon.

Right now, we've already begun working on integrating a "true" physics engine into Ca3DE, and I'll post more details about these exciting changes soon.
Work on the lighting and shadows code will begin as soon as the new physics code is finished. :up:

You're right, the details on the Devmaster.net site are terribly out of date and need a thorough update!

Independently from that, the SHL code is currently not active, but still there: CaSHL, the SHL-equivalent to CaLight, and general support for SHL-maps in the file formats etc. is still there and works, only the GPU shaders are currently missing. The performance of SHL rendering was cumbersome at the time I wrote my thesis, and I therefore omitted their shaders when I rewrote the Ca3DE Material System. (Also because the current trend is clearly away from lengthy precomputations, but towards immediate results by dynamic lighting.)
However, all related code is still in the latest Ca3DE code base, and is automatically available to those who obtain a source code license.

Wow the physics sounds great cant wait to see more

TRUE physics! sounds awesome! me too I can't wait!
