Indigo 0.7 test 1
Posted: Wed Jan 10, 2007 6:47 pm
Right, i'm getting bored just bugfixing and not releasing anything,
so here's 0.7 test 1.
There's a metric fuckton of new stuff, the big ones are
SSS + participating media (experimental), new media system, polarisation (experimental),
camera bloom, mem usage optimisation, autofocus, a glossy transparent material, instancing, a blend_material (allowing material trees)
NOTE: many stuffs may not work!!!! this is a TEST release!!
ANOTHER NOTE: your xml files will need to change, quite a lot
I'll be writing on how to use these features soon.
stuff that is currently broken:
* kdtree disk caching
* bidirectional stuff
* probably lots of other stuff

Changelog:
v0.7 test 1
* improved disc sampling
* added in polarisation simulation
* specular tag of phong removed; use ior instead.
* added bloom tag to camera tag.
* added in precedence for transparent specular materials
* some small speedups for kdtree traversal
* added in blend material
* added diffuse_transmitter material
* added autofocus option for camera
* (re)added ply model loading
* fucked around with mesh loading code
* meshes should use less memory now
* raises fatal error on unexpected element when parsing scene xml
* throw error on texture missing, instead of issuing warning
* changed how burn is used, the burn value is now based on the average image luminance instead of the max over all the pixels.
* Added in new 'medium' object and changed how specular materials work.
* changed absorption to absorption_coefficient_spectrum
* added glossy_transparent material
* added uniform spectrum type
* Added internal mesh instancing
* raises error on non-orthogonal rotation matrix
* added SSS and participating media in general.
* added normal_smoothing boolean element to mesh element.
* removed enable_normal_smoothing element from model element
* added fatal error if no lights in scene
* possibly fixed specular bump mapping bug (was not binding uv coords)
* removed gain from texture elements, using a, b, c polynomial coefficients instead
* fixed bug where reverse gamma correction was applied multiple times to same texture.

Some documentation updates:

------------- XML Stuff ------------
There's heaps of test scenes to look at if you're in doubt about how to do something, but here's some changes:
You'll need to add
or
to each mesh element.
Camera with bloom:
to use autofocus (sets focus_distance by tracing ray)
in camera element.
To define a medium, in this case glass:
The Specular material is now defined like this:
Glossy transparent like this:
A medium with SSS:
(not sure if SSS is working right now tho)
Blend material, in this case using a texture to blend between the
materials named 'a' and 'b':
EDIT: updated with fixed example.
so here's 0.7 test 1.
