OpenGL rendering is now done into sRGB framebuffer. OpenGl_ShaderManager::prepareStdProgramFboBlit() has been extended by programs resolving MSAA texture and applying gamma correction as fallbacks. Quantity_Color definition has been modified to store RGB components in linear color space within Quantity_TOC_RGB type. Standard colors defined by Quantity_NameOfColor enumeration has been updated accordingly. New Quantity_TOC_sRGB type has been introduced to handle RGB components in non-linear sRGB color space. OpenGl_TextureFormat class definition has been moved to dedicated files. New method OpenGl_TextureFormat::FindFormat() replaces OpenGl_Texture::GetDataFormat(). New method OpenGl_TextureFormat::FindSizedFormat() replaces OpenGl_FrameBuffer::getColorDataFormat() and OpenGl_FrameBuffer::getDepthDataFormat(). Graphic3d_TextureRoot::IsColorMap() - introduced new property defining if RGB(A)8 image formats should be loaded as sRGB(A) textures or as data RGB(A) textures. OpenGl_Texture initialization methods have been extended with new theIsColorMap argument. vreadpixel - added argument -sRGB printing color in sRGB color space. Test cases have been updated to new sRGB rendered results.

|
|
// If the compound does not contain nested compounds then adds it
|
|
// as no-assembly (i.e. no individual labels for sub-shapes), as this
|
|
// combination is often encountered in IGES (e.g. Group of Trimmed Surfaces).
|
|
// If the compound does contain nested compounds then adds it as an
|
|
// assembly.
|
|
// The construction happens bottom-up, i.e. the most deep sub-shapes are added
|
|
// first.
|
|
// If theIsTop is False (in a recursive call) then sub-shapes are added without
|
|
// a location. This is to ensure that no extra label in the XDE document is
|
|
// created for an instance (as otherwise, XDE will consider it as a free
|
|
// shape). Correct location and instance will be created when adding a parent
|
|
// compound.
|
|
// theMap is used to avoid visiting the same compound.
