Creating 3D Models for a Game using Blender and Bloom Effect in Graphics [closed]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 11 years ago.

I am开发者_Go百科 creating a game that requires heavy use of 3D Models. I started using Blender for creating models. Here are some models which I came across while developing a model

1. I need to create a model of a Cube with Horizontal Grooves/Depressions and impart glow to those Grooves. I went through a blender tutorial which described how to impart glow to certain objects but I don't how to create a Cube with Grooves/Depressions.

2. Second Question is related more to the field of Graphics. What is Bloom effect ? Is it related to lighting models in any way? How do I impart it using Opengl and C++ ?

I can only try to help you with your second question, since I'm not experienced with blender. A Bloom effect is a graphical effect to visualize strong light sources. It is often implemented as a shader. The wikipedia article is actually quite interesting.

You should be able to find tons of tutorials for both OpenGL and DirectX respective their shader languages. A quick search provided these, which look promising:
