This document aims to document how to support 2D objects positions in a 3D engine supporting different resolutions and aspect ratios.   This is the solution I have currently adopted in our PATRIA 3D engine and it is not for sure the best solution available there.   In such conditions it is quite difficult to […]

 I recently faced some memory corruption problems on my PATRIA 3D engine which are quite painful to be solved. Luckily I started using Valgrind, an opensource dynamic analysis tool which can debug the memory allocation of a typical C program. Valgrind is free and can be downloaded at this URL. http://valgrind.org/ The very interesting part […]

 A video o the Fantasy Racing Alpha 2.2   This version shows the following:   – New Blinn-Phong based shader for 3D objects rendering – New Linear Fogging – New depth culling – New HUD for the game – Track ground and Borders

Here we are, the version A3.0 of the new teamnovasoft game Fantasy Racing. Many optimizations have been done. Now the new engine implements the uber model technique which aggregates multiple 3D meshes into a single object in real time in order to perform massive OpenGL Batching and let the GPU operate at its maximum power. […]

 I always loved the C language, it is a pure passion for me, I always use this fantastic language when I need to develop real time applications. These days, I am very focused on my new 3D engine called PATRIA and I am now doing some housekeeping procedures in order to avoid memory leaks and […]

 I am extremely happy to announce the release of the Version Alpha 1.0 of the PATRIA 3D engine. The new version introduces a brand new selection system in the PATRIA engine based on the color picking / render buffer rendering. The whole PATRIA engine has been modified to support this new technique and now it […]

 We have recently released the new version of the PATRIA engine, the version Apha 0.5.   This video demonstate what the engine is capable to achieve applied to a cross platform game called Fantasy Racing.   The game will be released soon on the Android platform.   Cheers. Mao

 Extreme Cuber Racing Alpha version 0.3   I am very proud to announce you that all the changes required in order to be OpenGL ES 2.0 compliant have been completed.   The new PATRIA engine now supports:  – Hemispherical Lighting Shader – Texture 2D-3D and cube mapping support – Custom ModelMatrix – ViewMatrix algorithms – […]

  Last night I have completed the whole set of matrix transformation functions, the new custom modelview matrix stack (with my own version of the PUSH/POP matrix) and a temporary version of the hemi light  shader to support the new OpenGL Version.   so far, so good, I have still the strange artifacts I was […]

Today I was finally able to upgrade the MESA3D libraries using DRI HW accelleration on my Ubuntu 10.10 installation.   The upgrade fixed a lot of problems, in particular the rendering of the meshes now don’t have anymore the strange artifacts of polygons blinking around. Not bad, nice start.   Having finally apparently solved the […]
