Maciej Sumiński 00847a8aed Colors are stored as unsigned bytes instead of floats. 2013-06-30 22:45:31 +02:00
Maciej Suminski 58de62aacc High contrast mode with showing the selected layer on the top. 2013-06-26 16:31:52 +02:00
Maciej Suminski 1367d33cd8 Small speed up for the color change function (OpenGL_GAL). 2013-06-26 10:43:58 +02:00
Maciej Suminski db74de74f5 Added possibility to change cached layer color (for the purpose of high contrast display). 2013-06-25 17:12:54 +02:00
Maciej Suminski 83f5bd60c1 Moved fields containing information about currently used color, shader and transformation for vertices from VBO_ITEM to VBO_CONTAINER (OPENGL_GAL). 2013-06-19 10:50:46 +02:00
Maciej Suminski cd517f67db Added VBO_CONTAINER as a faster storage for vertices (OPENGL_GAL), tuned for exchanging data with GPU. 
Removed a few unnecessary variables and fields from OPENGL_GAL.
Added function GAL::ClearCache() for freeing memory used by cached items.
Fixed a few memory leaks (tesselator, PAINTER's settings & VIEW_ITEM's groups).
Changed a few functions into inlines.

Maciej Suminski 8742dae4a4 Removed indices storing from VBO_ITEM as they are always consecutive numbers. Removed storing pointers to VBO_ITEMs that have to be drawn - instead they are memcpied to mapped GPU memory. 
Some functions of VBO_ITEM became inline.

Maciej Suminski 8e1fe5d766 Changed data structure in VBO_ITEM. 2013-06-05 10:48:30 +02:00
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.

Maciej Suminski 7a1718d0f5 Changed functions for adding vertices in VBO mode to make code easier to read and understand. 2013-05-16 14:47:34 +02:00
Maciej Suminski 733e5a55e3 Faster way of caching items for OPENGL GAL. 2013-05-16 10:35:16 +02:00
Maciej Suminski c9f9c4ddbc 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
Maciej Suminski 1b1216e53d Modified SetOffset (VBO_ITEM/OpenGL GAL) function. 2013-05-14 10:41:05 +02:00
Maciej Suminski a6c8beb73b Drawing tracks using PushVertices, added some comments, fixed formatting. 2013-05-14 10:38:25 +02:00
Maciej Suminski 32784ea191 Added possibility of adding multiple vertices to VBO_ITEM at once 2013-05-13 11:14:35 +02:00
Maciej Suminski e8f33ac903 Fixed memleak, removed excessive recaching, still there is a problem with Cairo caching 2013-05-10 16:05:40 +02:00
Maciej Suminski 191cb40e79 Introduction of VBO. Now only tracks are rendered in a very simple way. 2013-04-30 15:59:32 +02:00
