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 update: Bloom and Cascaded Shadow Maps

Bloom Filter The bloom filter makes bright objects glow and bleed through other objects positioned in between them and the camera. It is a common post-processing effect used all the time in video games and animated movies. The demo supports …...

OpenGL terrain renderer: rendering the terrain mesh

In this post I’ll discuss how I setup and render terrain mesh in the OpenGL terrain rendering demo. Most of the relevant code for this is in the ter-terrain.cpp file. Setting up a grid of vertices Unless you know how … Continue reading →

Example: Run an OpenGL (ES) compute shader on a DRM render-node

It has been a long time indeed since my last entry here. But I have actually been quite busy on a new adventure: graphics driver development. Two years ago I started contributing to Mesa, mostly to the Intel i965 backend, as a member of the Igalia...

vulkan/wsi/x11: Smplify implementation of vkGetPhysicalDeviceSurfaceFormatsKHR

This patch simplifies x11_surface_get_formats(). It is actually just a readability improvement over the patch I provided earlier this week (750d8cad72). Reviewed-by: Eric Engestrom

vulkan/wsi/x11: Fix behavior of vkGetPhysicalDeviceSurfacePresentModesKHR

x11_surface_get_present_modes() is currently asserting that the number of elements in pPresentModeCount must be greater than or equal to the number of present modes available. This is buggy because pPresentModeCount elements are later copied from the...

glsl: inspect interfaces in contains_foo()

When checking if a type contains doubles, integers, samples, etc. we check if the current type is a record or array, but not if it is an interface. This commit also inspects if the type is an interface. It fixes...
