===Week 5 report===<br><br>==This week==<br>*Gathered some scenes (very few.. i was expecting to get a bigger community feedback..) and made other machine ready for testing - Test stuff is done. <br>*Earlier on the week I also looked on how to generate false-color images (i used UncleZeiv code as reference, but I get a crash when trying to enable a new added SCE_PASS_*, since I wasnt able to debug it, I gave up on that addition, thought it could be useful)<br>
Anyway optimization phase starts now.<br>
<br>*coded a raytree-builder helper "class", to make it easier to build trees<br>(currently suports only generic implicit tree building)<br><br>*coded a BVH tree for raycasting (based on BLI_bvh), but more generic in the aspect of trying build methods and data organization.<br>
<br>*profiled a few renders.. most time spend on ray-bb intersection<br><br>*tested latest build with the scenes<br><a href="http://andresp.no-ip.org/soc2009/btest/html/test_real">http://andresp.no-ip.org/soc2009/btest/html/test_real</a><br>
<a href="http://andresp.no-ip.org/soc2009/btest/html/test_concept">http://andresp.no-ip.org/soc2009/btest/html/test_concept</a><br><br>fixed some bugs and found a big regression (happened after merging from 2009-06-20 until 2009-07-02) on the "remembering past" scene, which seems to be related with some faces that are created and that may be "destroying" the tree, but I am not sure about.<br>
<br>==Next week==<br>*Find the reason of "remembering the past" slowdown..<br>*Implement a BIH<br>*Try diferent build methods (SAH, both on bvh and bih)<br><br>==questions==<br>none<br><br>==shedule==<br>First 2 phases concluded.<br>
