From Revision 12

Rev	Summary	Authors	Date
12	Ring shadow implementation: Ring shadow implementation: * Added axial tilt to planets (now planets have a complete transformation pipeline, instead of simple position) * Added saturn rings rendering (no depth buffer, so in front of planet) * Added ring shadows on planet * Added planet/moon shadows on ring	Jörg Müller	11 years ago
11	Analytical Rendering working nicely now: Analytical Rendering working nicely now: * Depth sorting * Planet distances in Model Koordinates (N*N instead of N texture memory, but no need for matrices in shaders anymore)	Jörg Müller	11 years ago
10	Fix for infinite shadow volume calculation without infinite ... Fix for infinite shadow volume calculation without infinite projection matrix. Also forgot some files during the last commits.	Jörg Müller	11 years ago
9	Quickly fixing lambert calculation of shaders. Quickly fixing lambert calculation of shaders.	Jörg Müller	11 years ago
8	Matrix4 minor bugs fixed Matrix4 minor bugs fixed Finite Shadow volume generation fixed Planets have Names now Vector4 fixed w calculation Solar System Data Added ((C) Wikipedia) Removed old planet, moon, sun Fixed lighting problems Added a default Shader (=> Min. OGL 2 for rendering) Analytical handles many shadow casters now, in case of multiples per point: least illumination is taken; self-shadowing is currently disabled Adapted viewing for huge distances (zoom, near/far plane) Implemented Look At planets/moons Implemented Planetary positioning Implemented UI to toggle: wireframe, ipm, stencil volume drawing, stencil reverse, shadow style	Jörg Müller	11 years ago
7	Framework updates: Framework updates: * Matrix class for easy CPU computation Planets: * Have periods and parents now * Parents determine position origin * Period + time determine position around parent (circular) Shadow Volumes: * CPU shadow volumes get updated each frame * GPU shader works with Renderer class options now Renderer: * FOV: determines zoom level * Time: Planets is animated now at selectable speed * Shader loading (and failback) got corrected * Corrected Model/View matrix problems in GPU shaders	Jörg Müller	11 years ago
6	Bugfix for non-shader users. Bugfix for non-shader users.	Jörg Müller	11 years ago
5	First version of analytical shadows, lots of problems though... First version of analytical shadows, lots of problems though: - Only one specific shadow caster supported at the moment. - View depedency - need to split model and view matrix for the shader. - Other problems: current code has some problems with other examples than the one committed (like different radius and distances).	Jörg Müller	11 years ago
4	Stencil shadow code cleanup. Stencil shadow code cleanup.	Jörg Müller	11 years ago
3	Stencil shadows using shaders (especially a geometry shader ... Stencil shadows using shaders (especially a geometry shader to calculate the shadow volume) Minor details: * More faces for the spheres * Code cleanup * Adjacency for drawing the spheres * Light position in geometry shader is world space, not eye space	Jörg Müller	11 years ago
2	Stencil shadow now working! Yay Stencil shadow now working! Yay	Jörg Müller	11 years ago
1	Stencil shadow volumes first implementation. Stencil shadow volumes first implementation.	Jörg Müller	11 years ago
