Light Map Editor ThingSo last week I started on an editor/light map tool thing. Think GTKRadiant (for now) - but eventually I want to develop it into something that work with Physically Based Rendering. Maybe add some animation tooling as well. My first set of goals are: - Write a tool that generates ray cast lightmaps - Extend this to use radiosity - Write a CSG editor That will keep me occupied for a while

That sounds complicated! Good luck.

Been a good day. - So I have worked on getting mesh loading working. - Added some more GUI elements. - "Generate" a Lightmap texture - currently it is just a red checker board texture  Lightmapping usually uses a 2nd set of UV coordinates for referencing a lightmap texture. There are a number of reasons for this, but the main one is that geometry shouldn't (usually) share UV coordinates in the same lightmap. Luckily for me, the robot model I am using has 1 set of coordinates with no overlaps - so for now I can use the UVs provided with the model for generating light maps. Later on I will need to figure out a way to generate a second set specifically for lightmap generation. You can see the UV nicely unwrapped in the image below.  Next step is to update the texture generation to actually generate a lightmap instead of just a checker board pattern.. yay. |

So I have made some progress into a slight diversion.. I have started building a ray tracer - which will eventually feedback into the light map generation stuff. Anyway, some screenshots:

Got a first render of some spheres with perfect diffuse lighting.

A few more significant things done. I refactored all of the ray casting code out of the ray tracer and into a collision detection system (which will also drive the physics system.. when I get around to that) On the visible front: - Linear fog - Circle (on a plane) - Depth sorting (Which is why the spheres get chopped in half by the circle!)

With a fair bit of wrangling.. we have shadows: In the image above you can see the "eye" ray and "shadow" ray. This is only diffuse at the moment. So there is no refraction/transmission or reflection (specular) |

Added support for axis aligned box primitives:

Replaced the global directional light with place able point lights: In this scene I have created a Cornell Box - which is a good setup for testing how renders compare with real life. Yes.. I will get around to changing the colours from red.. soon! |

Multiple lights work I have added a sphere primitve Super basic material's (Colour per primitive type)
