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.

In the previous post in this series I introduced how to render the shadow map image, which is simply the depth information for the scene from the view point of the light. In this post I will cover how to … Continue reading →

There are several methods to create and display a terrain, in real-time. In this post, I will explain the approach I followed on the demo I’m writing for my work at Igalia. Some work is still in progress. The terrain had to meet the following...
SAMPLES and NUM_SAMPLE_COUNTS queries accept internalformats which are defined as color-, depth- or stencil-renderable. RGB9_E5 is marked as non color-renderable in OpenGL 4.6, however if the EXT_texture_shared_exponent extension is exposed it must be...Antía Puentes20/02/2018

Although seems somewhat too specific, with mesa HEAD at: 766589d89a211e67f313e8cb38f2d05b09975f96 this test crashes, so it would be good to include a test for this. v2: Added comments that clarify the array index used (Fabian) Reviewed-by: Fabian BielerAlejandro Piñeiro24/01/2018
vk_error() is a macro that calls __vk_errorf() with instance == NULL. Then, __vk_errorf() passes a pointer to instance->debug_report_callbacks to vk_debug_error(), which segfaults as this pointer is invalid but not NULL. Fixes: e5b1bd6ab8 "vulkan:...Samuel Iglesias19/01/2018
