* Fix the missing spot shadow when DEBUG_SHADOW is turned onztenghui2014-03-171-1/+3
| | | | | | | In the current design, this error should be tolerated since the delta should be small enough. So we should not return here. Change-Id: I251db2882b331d37ae7f0896e9aa95d69a5650da
* Create one hole inside the umbra area to avoid overdraw.ztenghui2014-03-171-60/+105

* Fix orthographic shadows projection, simplify shadow reorderingChris Craik2014-03-121-4/+4
| | | | | | | | | Separate matrix passed to shadow system into two parts, one for transforming the polygon XY points (using the actual draw matrix) and a separate one which respects correct 4x4 3d rotations and translations for determining Z values. Change-Id: I7e30a84774a8709df6b2241e8f51fc5583648fe8
* Improve shadow tessellation performanceChris Craik2014-03-111-118/+129
| | | | | | | | - Tune and simplify shadow parameters - Remove additional inner rings - Improve polygon ray casting algorithm Change-Id: If0f28b2d66ae0480b675942bb65e8fcd2864425d
* Use pre-computed index to draw the shadow.ztenghui2014-02-251-104/+37
| | | | | | | | Also draw the umbra part as triangle fans instead of zig zag fashion. b/12840179 Change-Id: Iaa5d15e77351acdd71f076bd8f9bb2d4d2b92faf

| | | | | | | | | | | | This fixed most of the issues when the light's Z postion is low. Change-Id: If49afbf8aa90b1ce32fd628a62ed982a1a473da2
