virtual ~CRenderer();
};There are couple of utility shader functions available. They allow to find out at which part of the block current pixel is.
int BlockPointLocation(vec2 p);
This function gets current pixel coordinates(which could be found in var_FormCoord variable if you created shader program using the second(with one argument, method) and returns integer indicating where point is. Possible results are: 0 - point is on left border, 1 - point is on top border, 2 - point is on right border, 3 - point is on bottom border, 4 - point is inside, 5 - point is outside. When you create complete custom shader(using the first method with 3 arguments) you should specifiy options described below to be able to use this function properly. Here they are.
vec4 app_BlockRect; Block rectanglevec4 app_BlockBorder; Block border widthsvec4 app_BlockRadius; Block corner radiusesvec2 app_BlockInnerEllipse[4]; Precalculated value. You can find how to calculate in in renderer implementation source codevec2 app_BlockCornerCenter[4]; Precalculated value. You can find how to calculate in in renderer implementation source codevec2 app_BlockOuterRCenter[4]; Precalculated value. You can find how to calculate in in renderer implementation source codebvec4 app_BlockHasInner; Whether inner corner is round or sharp. You can find how to calculate in in renderer implementation source code
vec4 BlockPointColor(vec2 p);
This function gets current pixel coordinates and return corresponding color depending on where the pixel is of the block. The same conditions are applied to this function as they are for previous one. Additionaly it requires one more option to be specified.
vec4 app_BlockColors[6]; Colors for block parts
All this options are automatically added to your shader program if you created the program using method with one argument. If you would like to add this utilities to your extended shader program created by extended IRenderer::ShaderProgramCreate method, you have to set the last utils argument to true and also specify {utils} placeholder in your shader program text where the utilities should be injected.
When you create shader program using second creation method the source code should have this function
vec4 CalculateColor(vec2 tex_coord, vec2 form_coord, vec4 color);
It will be supplied with pixel texture coordinates, pixel form/render target coordinates, and interpolated color. The function should return final premultiplied color(red, green, and blue components should be multiplied by alpha; if you get color from texture, do not premultiply it because all textures have already premultiplied pixels). Also block and mask will be applied as well. Additionally in this case following option name should not be used: app_BlockPointLocation, app_Mask, app_MaskSize, app_FormToGL, app_Primitive, app_MaskInv.
The minimum shader language version should be #version 310 es.
This renderer uses following texture indices when performing drawing operations. Either avoid using them when activating textures for your custom shader programs or consider they may be changed during drawing operations described below.
The renderer does not provide any checking of arguments validity. A caller is responsible for such a checking. If you use invalid argument in most cases nothing will be drawn. But in some case you may get fatal error. For example if you use nullptr instead of texture.
