Particle System, free camera and billboard implemented by OpenGL

It is nice to return to OGL again, especially when using ogre3d for a while. I want to implement many things by myself.

The progress of using OGL in Win32 is as follows ~)

 

1. cegui Interface

2. Frame Rate Calculator

3. self-owned cameras

4. sky box

5. Point and axis billboard

6. Particle System

 

The parameters of the particle system are as follows: (you may have to modify them later ~)

 

1. Particle

Attribute: whether to activate, size, life value, attenuation rate, color, location, speed, and acceleration

Method: update and rendering

 

2. Particle System

Attributes: number of particles, particle size, system location, particle source region, average particle attenuation rate, and average particle initialization Rate

Whether to cycle, whether the particle is color, particle color, gravity, particle set, particle texture

Method: setter and getter of the basic attributes, set the position, translation, update and render particles, and reset the particles (initialization)

 

, As follows:
