Norman Feske	c0e303632e	gems: fix clipping in polygon_gfx/line_painter.h ... This clipping check happened to wrongly test the surface's clipping area instead of the by 1x1 pixel reduced 'clip' rectangle.	2022-09-21 12:19:10 +02:00

Norman Feske	55dc3abf00	Move gems/bezier.h to util/bezier.h (in repos/os) ... This way, os components (i.e., input_filter) can use it for nonlinear interpolation.	2017-11-09 12:18:43 +01:00

Norman Feske	259b127f96	Polygon drawing and rudimentary 3D routines ... This patch adds two new painters located at gems/include/polygon_gfx. Both painters draw convex polygons with an arbirary number of points. The shaded-polygon painter interpolates the color and alpha values whereas the textured-polygon painter applies a texture to the polygon. The painters are accompanied by simplistic 3D routines located at gems/include/nano3d/ and a corresponding example (gems/run/nano3d.run).	2015-07-07 19:48:04 +02:00
