Maciej Suminski 28511cf4fe Introducing shaders. ... Shader's parameters are stored in VBO_ITEM. Changed VBO_ITEM data structure. Added UseShader() function for selecting shader for a given VBO_ITEM. Added one main vertex & fragment shader program to be used for with all kinds of items (type of shader is selected using attributes that are stored in VBO). Currently available shaders are: at-least-1px-width line, filled circle and stroked circle. Removed unnecessary param (aDepthOffset) from a few functions (OPENGL_GAL::drawSemiCircle(), OPENGL_GAL::drawLineCap()). Removed function OPENGL_GAL::DrawRoundedSegment(). Changed some asserts to debug info or error log.		2013-06-04 15:58:53 +02:00

glm	Added functionality for transformation of VBO vertices, extended functions like translate, rotate, scale using glm library. Removed D() macro, as it was not used, but in conflict with glm library. Added VBO_ITEMs for circles, semicircles. Now almost everything is drawn using VBO (besides polygons and grid).	2013-05-15 16:48:10 +02:00
