mediump vs highp precision on Embedded GPUs

There are a lot of  tests on GPU performance, in terms of how many operations per sec (rendering, float arithmetic, etc..), but not a lot on quality and precision. Most would argue that such a benchmark is not very relevant, well that is true in general cases but not all (actually its like having 5k [...]

Resolution independent curves @ GraphiCon 2011

Will be presenting by the end of this month the paper behind the Resolution Independent Fonts, Curve, and UI rendering API added recently to jogl. Title: Resolution Independent NURBS Curves Rendering using Programmable Graphics Pipeline Abstract: Non-Uniform Rational B-Splines (NURBS) are widely used,especially in the design and manufacturing industry, for their precision and ability to represent [...]

Siggraph 2011 – Vancouver

Once again siggraph was great… didnt get time to see Vancouver but it looked nice! had the pleasure to co-present with Sven the latest development on Jogamp.org, mainly JOGL highlighting the newly added support for embedded devices (linux ARM and Android) and the new Resolution independent Font and User Interface. In all, it was a [...]

JogAmp @ Siggraph2011

Cross posting announcement with Sven Gothel. ++++++++++++++++++++++++++++++++++++++++++++++++++++++ Jogamp will be at Siggraph this year after the great success of last year’s BOF. JogAmp: 2D/3D & Multimedia Across Devices Tuesday, 9 August | 2:30 pm – 4:30 pm | Vancouver Convention Centre JogAmp provides JOGL (OpenGL), JOCL (OpenCL) across devices on top of Java. Showcasing Resolution [...]

GPU based User Interface – WIP

One the goals behind the work done in GPU based Curve Rendering, was the ability to investigate the possibilities regarding GPU based user interface in a 2D/3D scene – ontop of jogl. As a test, pushed to repo a testcase for rendering a button with a label, using the Resolution Independent Region/Text Renderer. https://github.com/rsantina/jogl/commit/e6de1dcd253ef4d6ba9f584b4ed3540c85c66d2c Screenshots: [...]

GPU based Resolution Independent Font & Curve Rendering – initial Release

Below is about the latest project done by Sven Gothel and myself, which is now published/merged in JogAmp – Jogl Project. The story: At first we started this project as an idea, started with a chat with Sven on possible ways to by pass the Microsoft patent on GPU Curve Rendering. So after digging into [...]

GPU Resolution Independent Curve Rendering – Brief

In the past couple of weeks, I worked on developing a new technique to create an API for resolution independent curve bounded regions and text in general.  The main goal of this project was to move out of the Microsoft Patent Loop/Blinn approach which uses Bezier (Quadratic/Cubic) curve rendering to solve the problem. To by-pass the [...]

3D Scene Navigation standards

Picking up a new software and navigating thru the scene should be easy and intuitive.  Most of the tools out there are picking up a standard set of navigation modes which are the bare essential for a good user experience with your tool. Sure, some tools add a set of “identity”  navigation mode which identify [...]

MM Adaptive Rendering using JOGL and Newt

Was working recently on creating an adaptive renderer, using JOGL. The goal of this project was to ensure high frame rate and usability while walking thru a model of a large data set. Ideally, containing approx. a million+ complex geometric objects. What follows is a description on how it was done. (you might see this [...]

Creating a JOGL Eclipse Project

Below is a how to create an eclipse project for JOGL project, www.jogamp.org. Why isnt it on github….well since eclipse takes full paths of the src directories, you would need to practicaly re-do it after fetching the project. 1- After downloading the source code, create an eclipse workspace in the jogl directory ..or anywhere else.2- [...]
