Suddenly noticed that while running, memory consumption is slowly but steadily creeping up: which can only mean one thing: Well, then we need to find (detect) and fix it (or them). Some sort of memory leak detection tool would help. Visual Studio offers it's own set of "CRT debug heap functions". However, I was unable […]
Another (maybe the most) critical component of a realistic image is SHADOWS. The common approach is "shadow mapping". The algorithm consists of two passes. First, the scene is rendered from the point of view of the light source. Only the depth of each fragment/pixel is calculated. The scene is then rendered as usual, but with […]
Next step is to replace these square models by something more actual. For example, by this: I picked specifically this model for it's challengingly curved shapes. Just in case, this is 1935 Duesenberg SSJ Speedster, 1:64 scale model. In order to implement that, we'll need to extend our ModelBuilder and ModelLoader functionality. Also we'll need […]
Now we are ready for more complex models, consisting of several elements with individual behavior. For example - car, where body will be a parent (root) element, and wheels - child elements. For both, body and wheel, we'll need separate model descriptors and separate classes, which will handle their behaviors. 1. In Windows File Explorer […]
Just to make sure that we are on the same page, let's synchronize our environments. You can download full current Project repository from https://github.com/bkantemir/_wg37 Windows solution, x86: _wg37-main\a997modeler\p_windows\p_windows.sln Android solution, ARM64: _wg37-main\a997modeler\p_android\p_android.sln Important changes here: In order to untie the project from C:\CPP, all paths in projects properties were converted to relative form. Like ..\..\engine […]
Though the model is completely ready now, still we have 1 more issue to resolve: Currently our model consists of 316 vertices and 144 triangles (432 indices). Actually, not too much comparing to 3D editors. But still, how come so many?? Well, root box for instance: 6 sides, 4 vertices each = 24 vertices 12 […]
The model is almost ready. Two remaining missing pieces are: For clear-film we don't even need to write a new shader. We will use our "mirror" shader (as for gilded prints) with white noise as a main texture (uTex0) and will "translate" it to semi-transparent 8x1 texture glass01.bmp (uTex3), imitating glass reflection. It's a plain […]
Here I want to add a golden sealing ribbon on the pack. It will be a line, a sequence of points instead of regular triangulars mesh. It will require: A set of new tags in ModelLoader New lineWidth property in Material class In DrawJob we'll need to adjust lineWidth depending on distance Additional shader's functionality […]
Sure, I had doubts regarding my initial OpenGL ES choice. Now I have some answers: Vulkan Is it good? Well... Yes: However, I'm mainly interested in how cross-platform it is. Unfortunately, not exactly. Besides: Actually, quite enough to exclude it from my consideration… OpenGL ES The situation around OpenGL ES seems to me much more […]
A few days ago I started receiving the following messages from Windows Defender: Microsoft Visual Studio: Unable to start program 'C:\CPP\...\w.exe'. Operation did not complete successfully because the file contains a virus or potentially unwanted software. At the beginning it didn't bother me much, since project rebuild usually helped. But finally Defender "promoted" me (along […]
