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 […]
We are STILL trying to "draw" the joint (slit) between the pack and the lid, as a small normal map applied to existing textured mesh's fragment. At this point we do have fragments with their own "native" Materials. In the last sample we just replaced them (Materials) by Phong green. Instead we need to use native Materials, but with added […]
Just a friendly reminder: we are still trying to "draw" the joint (slit) between the pack and the lid, as a small normal map applied to existing textured mesh's fragment. Like this: In previous chapter we implemented a concept of selecting and manipulating "marked vertices/triangles groups". So, now we can select one (in this sample - "box_right"), duplicate […]
Next I want to "draw" the joint (slit) between the pack and the lid, like a small normal map applied to existing textured mesh's fragment, not to entire mesh and not to VirtualShape as we did before. This will require a few new concepts. Windows 1. Start VS, open C:\CPP\a997modeler\p_windows\p_windows.sln. The first new concept - marked […]
Now I want to make gilded blazon and "Marlboro" sign on the front embossed. For this we'll use Normal Maps. That's a bluish images on the right: To burn them I used NormalMap-Online website. Default settings are for DirectX. For OpenGL - checkmark Invert R Click on the left picture to upload your own. You […]
Here I want to add gilded (golden) prints on the pack. For this we will need a way to modify projection's size and position (initially defined by VirtualShape). Our new root01.txt will be: 1. Copy this code to a Text Editor and save it (overwrite) to/as C:\CPP\a997modeler\dt\models\misc\marlboro01\root01.txt Please note: In previous samples we used gold01.bmp texture. But […]
Chroma keying, obviously, is a way of treating certain color as transparent one. In our case - green: Of course, after loading an image, before pushing it to a texture, we can easily scan it for green pixels and set their Alpha-channels to zero. But when GL rasterizer picks tUV coordinates near the green areas, […]
Our next goal is to move model building process out of TheGame class. We will need some kind of models text descriptor, XML format seems quite suitable. We will keep models descriptions outside of executable, in /dt folder. Then we'll need a class that will load, read and process these descriptors and build actual 3D […]
Here I want to add "reflection" and "over mask" shaders, each of which will double number of shader-programs. Correspondingly, we'll need a function which will load a group of shaders in 1 shot (for example - Phong or flat for different data feeds). Also, we'll need a function that will pick particular shader number depending […]
Here I want to render a bit more complicated white noise images. I want bigger dots with a soft transition between them. The task splits in following steps: Generate initial black/white image (as we did in previous chapter) Generate a GL texture out of it Make it renderable (associate a render buffer with it) Force […]
