OpenGl_Texture now uses GL_UNPACK_ROW_LENGTH on OpenGL ES 3.0 when necessary.
OpenGl_Texture::InitCubeMap() now allows uploading vertically-stacked cubemaps
without GL_UNPACK_ROW_LENGTH requirement.
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.
Font_FTFont now uses fallback fonts for characters from unsupported Unicode subsets,
managed by Font_FTFont::ToUseUnicodeSubsetFallback()
and Font_FontMgr::ToUseUnicodeSubsetFallback() option, enabled by default.
The fallback list includes common font families for Chinese, Korean and Japanese languages.
Font_FTFont::RenderGlyph() now supports FT_PIXEL_MODE_MONO input format used by some CJK fonts.
OpenGl_Font::createTexture() now limits single texture size to circa 4096 glyphs.
test/testgrid now expects test scripts being in UTF-8 encoding in sync with "DRAWEXE -f script.tcl".
AIS::InitFaceLength() - fixed usage of uninitialized result.
Graphic3d_RenderingParams::ToShowStats - new option displaying rendering statistics.
OpenGl_FrameStats - new class for accumulating frame statistics.
OpenGl_Context::FrameStats() provides an access to the frame stats
used for currently rendered context.
OpenGl_View::Redraw() and OpenGl_View::RedrawImmediate()
resets counters within OpenGl_Context::FrameStats().
OpenGl_Layer::UpdateCulling() - simplified resetting of culling state for cullable structures.
Graphic3d_AspectFillArea3d now stores array of textures.
Graphic3d_TextureParams stores texture unit for mapping texture.
OpenGl_Context::BindTextures() - context now manages the set of active textures.
Related code has been removed from OpenGl_Workspace.
OpenGl_Sampler has been extended to hold texture parameters structure.
OpenGl_Texture now holds OpenGl_Sampler instance as class field.
OpenGl_Texture inherits new class OpenGl_NamedResource and holds
texture identifier used for sharing resource in OpenGl_Context.
OpenGl_RaytraceGeometry now creates bindless textures taking
Sampler object directly from OpenGl_Texture.
OpenGl_Context::BindTextures() automatically recreates immutable
Sampler Object on texture parameters change.
Declared new structure OpenGl_ArbSamplerObject for platform-neutral
usage of related functionality.
Related functions are now loaded within OpenGL ES 3.0+.
Declarations.glsl - occActiveSampler has been renamed to occSampler0
with aliases occSamplerBaseColor (main) and occActiveSampler (for compatibility).
Additional texture samplers should be declared explicitly
within specific GLSL program as occSampler1, occSampler2, etc.
AIS_Shape and AIS_ColoredShape now computes Shaded presentation
with UV coordinates if texture mapping is enabled in Drawer.
vshaderprog now accepts Shader source code as parameter.
Enumeration Image_PixMap::ImgFormat, previously declared as nested
enumeration within class *Image_PixMap*,
has been moved to global namespace as Image_Format following OCCT coding rules.
The enumeration values have suffix Image_Format_ and preserve
previous name scheme for easy renaming of old values.
E.g. Image_PixMap::ImgGray become Image_Format_Gray.
Old definitions are preserved as depreacated aliases to the new ones.
for usage without OpenGL.
Split OpenGl_TextFormatter into Font_TextFormatter and OpenGl_TextBuilder.
Font_TextFormatter can format a text independetly of OpenGl now.
OpenGl_TextBuilder generates primitive array required for rendering text
using OpenGl_Font instance.
OpenGl_Context::init() - fix condition on initializing alien OpenGL context within core profile.
OpenGl_Font::renderGlyph() - use GL_RED data format in core profile.
OpenGl_Text::render() - do not use GL_ALPHA_TEST in core profile.
Test-case for issue #26424
OpenGl_Texture::Init() - initialize FBO textures with GL_TEXTURE_WRAP_ set to GL_CLAMP_TO_EDGE,
since some devices do not support GL_REPEAT (which is default) in such combination.
OpenGl_Font::createTexture() - define texture parameters explicitly.
OpenGl_FrameBuffer::Init() create Depth render buffer object instead of texture
on devices which do not support GL_DEPTH24_STENCIL8.
Image_PixMap::ImgFormat - extend enumeration by ImgAlpha and ImgAlphaF.
OpenGl_Workspace::setTextureParams() - specify GL_REPLACE for 1-component textures with disabled modulation.
OpenGl_Texture::GetDataFormat() - return GL_LUMINANCE format for ImgGray format and GL_ALPHA for ImgAlpha.
vmarkerstest - override pixel format for grayscale images to ImgAlpha.
Add test case bugs/vis/bug25544_graytexture.
OpenGl_Element destruction and resource deallocation methods now accept
a pointer to OpenGl_Context instead of a handle to avoid double deletion
of the context.
License statement text corrected; compiler warnings caused by Bison 2.41 disabled for MSVC; a few other compiler warnings on 54-bit Windows eliminated by appropriate type cast
Wrong license statements corrected in several files.
Copyright and license statements added in XSD and GLSL files.
Copyright year updated in some files.
Obsolete documentation files removed from DrawResources.
Added class Font_FTFont wrapper over FreeType face
Unify collections methods NCollection_Array1, NCollection_Sequence, NCollection_Vector:
declare Upper, Lower, First, Last, ChangeFirst, ChangeLast methods for all these collections.
Added method NCollection_DataMap::Find() with check key is bound + retrieve value within single call interface.
OpenGl_Context::ReleaseResource() method now supports lazy release of shared resources.
Added class OpenGl_Font which implements textured fonts support.
Added class OpenGl_TextFormatter for text formatting using OpenGl_Font.
OpenGl_Text was redesigned to use OpenGl_FontFormatter.
OpenGl_FontMgr class was removed.
All methods related to text rendered removed from OpenGl_Display class.
OpenGl_Trihedron and OpenGl_GraduatedTrihedron classes were redesigned
to use OpenGl_Text.
OpenGl_PrinterContext instance was moved to OpenGl_GraphicDriver fields
(eliminated usage of global instance).
Added test cases into 3rdparty/fonts grid to check different font styles
and perform FPS tests (no automated results - requires manual analysis
or snapshots comparisons).
Removed unused CSF_FTGL dependency.
OpenGl_Text::setupMatrix - do not apply floor for myWinZ
