mingw32 exists as a package for Linux. You can cross-compile and -link Windows applications with it. There’s a tutorial here at the Code::Blocks forum. Mind that the command changes to x86_64-w64-mingw32-gcc-win32, for example. Ubuntu, for example, has MinGW in its repositories: $ apt-cache search mingw […] g++-mingw-w64 – GNU C++ compiler for MinGW-w64 gcc-mingw-w64 – … Read more
Patience, technical skill and endurance. First point is that a DX Demo is primarily a teaching aid so it’s done for clarity not speed of execution. It’s a pretty big subject to condense but games development is primarily about understanding your data and your execution paths to an almost pathological degree. Your code is designed … Read more
Rendering outlines, unless you render only a dozen characters total, remains a “no go” due to the number of vertices needed per character to approximate curvature. Though there have been approaches to evaluate bezier curves in the pixel shader instead, these suffer from not being easily antialiased, which is trivial using a distance-map-textured quad, and … Read more
You can’t easily communicate back to the CPU from within GLSL. Using glslDevil or other tools is your best bet. A printf would require trying to get back to the CPU from the GPU running the GLSL code. Instead, you can try pushing ahead to the display. Instead of trying to output text, output something … Read more
glPolygonMode( GL_FRONT_AND_BACK, GL_LINE ); to switch on, glPolygonMode( GL_FRONT_AND_BACK, GL_FILL ); to go back to normal. Note that things like texture-mapping and lighting will still be applied to the wireframe lines if they’re enabled, which can look weird.
If I understand correctly, performance-wise, flipping the sign of Z and the depth test is nothing but changing a < comparison to a > comparison. So, if I understand correctly and the author isn’t lying or making things up, then changing < to > used to be a vital optimization for many games. I didn’t … Read more
