I'm a beginning rails programmer, attempting to show many images on a page. Some images are to lay on top of others. To make it simple, say I want a blue square, with a red square in the upper right corner of the blue square (but not tight in the corner). I am trying to avoid compositing (with ImageMagick and similar) due to perfomanc...
What tools are available to monitor graphics card memory usage in linux? ...
I was browsing this thread, which has good recommendation but a bit too general for me. So, if anyone has a collection of nice game programming feeds,please share them. :) (both general and specific topics are welcome) ...
What are the best libraries for creating pretty charts and graphs in a Python application? ...
I am writing a c# control that wraps DirectX 9 and provides a simplified interface to perform 2d pixel level drawing. .NET requires that I wrap this code in an unsafe code block and compile with the allow unsafe code option. I'm locking the entire surface which then returns a pointer to the locked area of memory. I can then write pixel...
As a developer completely void of artistic skills, it's frustrating building applications from scratch. I know there are several open-source template web sites to draw from, but are there any good books/tutorials/web sites that can turn a poor, artistically-challenged developer into a moderately-capable graphic designer? ...
Say I'm a one-person programming shop, and I need to get some graphics for an application: icons, backgrounds, etc. What are some of the things I need to know before I hire someone to do that stuff for me? How have some of you been burned when doing something similar? ...
Currently my app uses just Direct3D9 for graphics, however in the future I' m planning to extend this to D3D10 and possibly OpenGL. The question is how can I do this in a tidy way? At present there are various Render methods in my code void Render(boost::function<void()> &Call) { D3dDevice->BeginScene(); Call(); D3dDevice->...
I need to create a 2D int array of size 800x800. But doing so creates a stack overflow (ha ha). I'm new to C++, so should I do something like a vector of vectors? And just encapsulate the 2d array into a class? Specifically, this array is my zbuffer in a graphics program. I need to store a z value for every pixel on the screen (henc...
Is there a way to draw a line along a curved path with a gradient that varies in a direction perpendicular to the direction of the line? I am using the GDI+ framework for my graphics. ...
I have a noobish question for any graphics programmer. I am confused how some games (like Crysis) can support both DirectX 9 (in XP) and 10 (in Vista)? What I understand so far is that if you write a DX10 app, then it can only runs in Vista. Maybe they have 2 code bases -- one written in DX9 and another in DX10? But isn't that an over...
I woud like to create a cross-platform drawing program. The one requirement for writing my app is that I have pixel level precision over the canvas. For instance, I want to write my own line drawing algorithm rather than rely on someone elses. I do not want any form of anti-aliasing (again, pixel level control is required.) I would like ...
C++ just sucks too much of my time by making me micro-manage my own memory, making me type far too much (hello std::vector<Thingy>::const_iterator it = lotsOfThingys.begin()), and boring me with long compile times. What's the single best alternative for serious real-time graphics programming? Garbage collection is a must (as is the abi...
I wanted to "emulate" a popular flash game, Chrontron, in C++ and needed some help getting started. (NOTE: Not for release, just practicing for myself) Basics: Player has a time machine. On each iteration of using the time machine, a parallel state is created, co-existing with a previous state. One of the states must complete all the o...
Where may one find references on implementing an algorithm for calculating a "dirty rectangle" for minimizing frame buffer updates? A display model that permits arbitrary edits and computes the minimal set of "bit blit" operations required to update the display. ...
I'm looking for a good 3D Mesh library Should be able to read popular formats (OFF, OBJ...) Should support both half-edge structure and a triangle soup Should be tolerant to faults and illegal meshes. Basic geometric operations - intersections, normal calculation, etc' Most importantly - Should not be convoluted with endless template a...
Hey guys, I'm toying with the idea of volumetric particles. By 'volumetric' I don't mean actually 3D model per particle - usually it's more expensive and harder to blend with other particles. What I mean is 2D particles that will look as close as possible to be volumetric. Right now what I/we have tried is particles with additional l...
Most precompiled Windows binaries are made with the MSYS+gcc toolchain. It uses MSVCRT runtime, which is incompatible with Visual C++ 2005/2008. So, how to go about and compile Cairo 1.6.4 (or later) for Visual C++ only. Including dependencies (png,zlib,pixman). ...
My father is color blind and given that I work in games where the visuals are important, I've always wanted to write a filter for screen shots (or even some type of shader) that emulated different forms of color blindness. I've seen plenty of references but never have been able to track down algorithms. Any algorithms would be apprec...
If the major axis of the ellipse is vertical or horizontal, it's easy to calculate the bounding box, but what about when the ellipse is rotated? The only way I can think of so far is to calculate all the points around the perimeter and find the max/min x and y values. It seems like there should be a simpler way. If there's a function (...
