Graphics Pipeline and Rendering Technologies

High framerates, smooth animations, and quality display are key to user interaction. Igalia has years of experience building and optimizing many different parts of the graphics stack.

Companies developing software for mobile, embedded or desktop environments often find the graphics and rendering software stack to be one of their greatest challenges. The most successful devices and software platforms have optimized, frictionless user experience, including fast rendering and fluid touch interfaces.

At Igalia we have been creating high performance user interfaces and middleware for the past decade. Along the way, we've built accelerated compositors, eliminated hardware bottlenecks, optimized rendering of web browsers, and perfected font display.

Open source work is a part of our company culture, so we are long time contributors to and integrators of toolkits and APIs like Mesa, OpenGL, GTK+, EFL, Qt, Clutter/Cogl and Wayland. Some of our work includes:

  • Implementation of new standards such as WebGL and WebAudio, multimedia acceleration and GStreamer integration in WebKit
  • Maintenance of GStreamer support in WebKit
  • Accelerated large drop-shadows in web engines
  • Building cross-process graphics architectures and compositors for projects like WebKit2

We can help you ensure that your users have a compelling experience powered by an optimized graphics software stack.

OpenGL terrain renderer

Lately I have been working on a simple terrain OpenGL renderer demo, mostly to have a playground where I could try some techniques like shadow mapping and water rendering in a scenario with a non trivial amount of geometry, and … Continue reading...

One year of Mesa

Changes During the last year and something, my work at Igalia was focused on the Intel i965 driver for Mesa, the open source OpenGL implementation. Iago and Samuel were working for some time, then joined Edu and Antía, and then I joined myself, as the...

Story and status of ARB_gpu_shader_fp64 on Intel GPUs

In case you haven’t heard yet, with the recently announced Mesa 12.0 release, Intel gen8+ GPUs expose OpenGL 4.3, which is quite a big leap from the previous OpenGL 3.3! Although this might surprise some, the truth is that even if the i965 driver...

Introducing Mesa intermediate representations on Intel drivers with a practical example

Introduction The recent big news on the Igalia work on Mesa was that our effort getting the ARB_gpu_shader_fp64 and ARB_vertex_attrib_64bit extensions implemented for Intel Gen8+, allowed to expose OpenGL 4.2 for Gen8+. But I will let other igalians to...

arb_texture_barrier: count of elements need to be multiple of three

glDrawRangeElements is used to draw triangles so the count of elements needs to be a multiple of three, so we need to be careful when dividing by the number of draw range elements we want. Fixes the 40 failing subtests on i965. Reviewed-by: Andres Gomez

arb_copy_image-api_errors: fix one error check (INVALID_ENUM instead of INVALID_OPERATION)

This patch adapts the test to the last change on mesa. Copying the rationale on that patch here: For the case (both src or dst) where we had a texobject, but the texobject target was not the same that the method target, this spec paragraph was...
