Shooter (OpenGL Visual Demo)

Shooter (OpenGL Visual Demo)

This is a small demo of a first person shooter. There are two available weapons that are activated with the keys of the mouse. The ground is taken by an image gif and subsequently convert in heightmap. In the Data directory is present the program Bgif to effect the conversion. The demo occupies 208Kbytes.

Routine Description

AUX_RGBImageRec *LoadBMP(char *Filename) Loads a bitmap image (called by LoadGLTextures)

int LoadGLTextures() Load Bitmaps And Convert To Textures

void VectorNormalize() ..... Vector Functions (used by Luce)

void glPrint(char *ll,float x,float y,float z,float dim,float dir,float r,float g,float b) My routine for print with opengl :

Char *ll => the line

x,y,z => the coordinates

dim => the font dimension

dir => not used for now

r,g,b => the color

void Luce(double x, double y, double z,double dimensione,float r,float g,float b,float iox,float ioy,float ioz,int Tex) Adds a particle with:

x,y,z => Position

dimensione => Size

r,g,b => Color

iox,ioy,ioz => Camera Position

Tex => Texture Number
