Diagnose and understand your app’s GPU behavior with GAPID

0


Debugging in action, one call at a time

GAPID not only allows you to diagnose problems with your rendering commands, but
also acts as a tool to run quick experiments and immediately see how these
the changes would affect the framework presented.

Here are some examples where GAPID can help you isolate and solve problems with
your application:

What does the GPU do?

Why does not my text appear ?!

Working with a graphical API can be frustrating when you have an unexpected
result, be it an empty screen, an upside-down triangle, or a missing mesh.
As an offline debugger, GAPID allows you to track these applications, and
then inspect the calls after. You can follow exactly which order
produces the incorrect result by looking at the framebuffer, and inspecting the
state at that time to help you diagnose the problem.

What happens if I do X?

Use GAPID to edit the shader code

Even when a program works as expected, sometimes you want to experiment.
GAPID allows you to modify API calls and shaders at will, so you can test things
as:

What if I used a different texture on this object?
And if I changed the calculation of flowering in this shader?

With GAPID, you can now browse the appearance of your application without having
to recompile your application or rebuild your assets.

Whether you build a gorgeous new office game with Vulkan or a beautifully
immersive VR experience on Android, we hope that GAPID will save you time
and frustration and help you get the most out of your GPU. To begin
GAPID and see how powerful it is, download it take your
favorite application, and capture a
trace !

Developing for 3D is complicated. Whether you use a native graphical API or
By recruiting the help of your favorite game engine, there are thousands of graphics
commands that have to come together perfectly to produce beautiful 3D images on
your phone, your desktop computer or your virtual reality headsets.

GAPID (Graphical API)
Debugger) is a new tool that helps developers diagnose rendering and
performance issues with their applications. With GAPID, you can capture a trace
of your application and go through each graphic command one by one. This allows
you visualize how your final image is constructed and isolate problematic calls, so
you spend less time debugging by trial and error.

GAPID supports OpenGL ES on Android and Vulkan on Android, Windows and Linux.
