This is an extraction of the Mesa 3-D library's software rasterizer and offscreen rendering implementation of OpenGL 2.0 style APIs. The 7.0.4 release of Mesa is the original source of this code, although it has been scrubbed down and modded a little for the purposes of minimalism. (This fork is not affiliated with the Mesa project - for the modern implementation see https://mesa3d.org)

The goals of this particular fork are NOT speed, but rather a portable, reliable, self contained, cross platform rendering method that does not require ANY outside support from the OS or graphics hardware. The idea is to guarantee an application's ability to produce scene rasterizations as image data even when the primary graphics stack of the machine is unavailable. It also aims to be as trouble free as possible when it comes to things like API stability and maintenance requirements.

The core libosmesa library deliberately does not have ANY external dependencies on any libraries beyond the core C/C++ system libraries - this makes it as insensitive as possible to changes in operating system environments. Because displaying the image data on screen is outside the scope of libosmesa, it is also not tied to any operating system's window system API. It just hands the caller the rasterized image data - any subsequent display is up to higher layers of the application's library stack.

The examples directory DOES have some external dependencies on graphical toolkits, in order to provide some graphical application examples. The example building may be disabled by setting -DOSMESA_BUILD_EXAMPLES=OFF. The examples directory itself may also be removed completely if a project bundling the libosmesa sources doesn't wish to include it - the build system will adapt appropriately.

Source code changes are (or at least are intended to be) relatively minor and include things like static analyzer clean-ups and updating header includes to avoid accidentally including system versions of gl.h.

Fast Approximate Anti-Aliasing

VTK-style Fast Approximate Anti-Aliasing) has been integrated into OSMesa as an optional built-in post-processing feature. This integration provides automatic edge smoothing for rendered images with minimal performance impact.

Features

Integrated API: Enable/disable FXAA with a single function call
sRGB Color Space: Processes images in sRGB color space (matching VTK's approach) for improved visual quality
Automatic Application: FXAA is applied automatically when glFinish() is called
VTK-Compatible: Uses the same algorithm and color space handling as VTK's GPU-based FXAA

API

OSMesaFXAAEnable

void OSMesaFXAAEnable(GLboolean enable);

Enable or disable FXAA post-processing for the current OSMesa context.

Parameters:

enable: GL_TRUE to enable FXAA, GL_FALSE to disable

Example:

OSMesaContext ctx = OSMesaCreateContextExt(OSMESA_RGBA, 16, 0, 0, NULL);
OSMesaMakeCurrent(ctx, buffer, GL_UNSIGNED_BYTE, width, height);

/* Enable FXAA */
OSMesaFXAAEnable(GL_TRUE);

/* Render scene */
render_scene();

/* FXAA is automatically applied when glFinish() is called */
glFinish();

Color Space Handling

The implementation converts rendered images through the following pipeline:

Linear RGB (from OpenGL rendering)
→ sRGB (via gamma encoding for FXAA processing)
FXAA processing (in sRGB color space)
→ Linear RGB (via gamma decoding for final output)

This matches VTK's approach and provides better visual quality than processing in linear space, as FXAA's luminance calculations work better in perceptual color space.

Limitations

Currently only works with RGBA 8-bit unsigned byte buffers
FXAA is applied in-place on the framebuffer
Uses fixed parameters tuned for general-purpose rendering

FXAA Parameters

The implementation uses the following parameters (matching VTK defaults):

RelativeContrastThreshold: 0.125
HardContrastThreshold: 0.0625
SubpixelBlendLimit: 0.75
SubpixelContrastThreshold: 0.25
EndpointSearchIterations: 12

These parameters provide a good balance between quality and performance for typical 3D rendering scenarios.

A note about supported OpenGL versions:

Most documentation for the 7.x series of Mesa3D mentions OpenGL 2.1. The reason libosmesa does not report that version is the ARB_shading_language_120 feature was "not quite done" in Mesa3D v7.0.4. ARB_pixel_buffer_object and EXT_texture_sRGB ARE present, but without GLSL v1.20 proper OpenGL v2.1 support is a no-go. Implementing what is missing (or backporting it from newer Mesa3D versions) would most likely be a significant effort, and is not currently in the scope of the libosmesa effort.

A note about GL_ARB_framebuffer_object under OpenGL 2.0:

GL_ARB_framebuffer_object was originally defined as an extension layered on top of OpenGL 2.x and later promoted to core in OpenGL 3.0. libosmesa advertises this extension and implements the full entry-point set:

glIsRenderbuffer / glBindRenderbuffer / glDeleteRenderbuffers glGenRenderbuffers / glRenderbufferStorage / glGetRenderbufferParameteriv glIsFramebuffer / glBindFramebuffer / glDeleteFramebuffers glGenFramebuffers / glCheckFramebufferStatus glFramebufferTexture1D/2D/3D / glFramebufferRenderbuffer glGetFramebufferAttachmentParameteriv / glGenerateMipmap glBlitFramebuffer / glRenderbufferStorageMultisample / glFramebufferTextureLayer

Known limitations arising from the GL 2.0 context:

Multisample (GL_RENDERBUFFER_SAMPLES): GL_MAX_SAMPLES is 1. glRenderbufferStorageMultisample() accepts any sample count in [0, 1] and creates a single-sample renderbuffer internally; no real multi-sampling is performed. Requesting samples > 1 generates GL_INVALID_VALUE.
Layered / array textures (glFramebufferTextureLayer): Only GL_TEXTURE_3D layers are supported. GL_TEXTURE_1D_ARRAY and GL_TEXTURE_2D_ARRAY require OpenGL 3.0 and are not available.
Integer framebuffer formats (e.g. GL_RGBA8I, GL_RGBA8UI): GL_EXT_texture_integer is implemented. Integer renderbuffer formats (GL_RGBA8I/UI, GL_RGBA16I/UI, GL_RGBA32I/UI, GL_RGB8I/UI, GL_RGB16I/UI, GL_RGB32I/UI) are supported as FBO color attachments. Note: GLSL integer samplers (isampler2D, usampler2D) are not supported.
sRGB framebuffers (GL_FRAMEBUFFER_ATTACHMENT_COLOR_ENCODING): GL_ARB_framebuffer_sRGB / GL_EXT_framebuffer_sRGB are implemented. GL_SRGB8_EXT and GL_SRGB8_ALPHA8_EXT are valid renderbuffer formats. When GL_FRAMEBUFFER_SRGB is enabled, linear→sRGB conversion is applied before storing color data to sRGB-format renderbuffers. sRGB attachments report GL_SRGB encoding; linear attachments GL_LINEAR.
GL_FRAMEBUFFER_ATTACHMENT_COMPONENT_TYPE: Fixed-point unsigned normalized (GL_UNSIGNED_NORMALIZED) is supported for all standard formats. GL_EXT_texture_integer adds GL_INT and GL_UNSIGNED_INT for integer format attachments. Floating-point types are not available.

Applications that check for GL_ARB_framebuffer_object in the extension string (rather than checking GL_VERSION >= 3.0) will work correctly within the above limitations. All validation, completeness checks, and query functions conform to the GL_ARB_framebuffer_object specification.
