FORMAT
#include <Ninja.h> void njDrawPolygon3D(*p, n, attr) NJS_POINT3COL *p Int n Uint32 attr
PARAMETERS
- *p
- list of coordinates of vertices of a polygon to be drawn
- n
- number of vertices of a polygon
- attr
- attributes (specifies the drawing method)
RETURN VALUE
FUNCTION
- Draws a polygon of n sides.
- The following four attributes can be used.
NJD_DRAW_NORMAL Normal drawing. NJD_FILL Drawing with interior fill. NJD_TRANSPARENT Transparent drawing. NJD_USE_TEXTURE Drawing with texture.
These attributes can be used in mutually consistent combinations by using the "|" character as a delimiter.
EXAMPLE
int i;
NJS_POINT3COL p;
NJS_POINT3 point[4];
NJS_COLOR color[4];
p->p = point;
p->col = color;
p->tex = NULL;
p.num = 4;
for(i = 0; i< 100; i++){
int j;
p->p[0].x = njRandom()*1000.f-500.f;
p->p[0].y = njRandom()*1000.f-500.f;
p->p[0].z = -3000.f+(float)i;
p->p[1].x = p->p[0].x-polysize;
p->p[1].y = p->p[0].y;
p->p[1].z = p->p[0].z;
p->p[2].x = p->p[0].x-polysize;
p->p[2].y = p->p[0].y-polysize;
p->p[2].z = p->p[0].z;
p->p[3].x = p->p[0].x;
p->p[3].y = p->p[0].y-polysize;
p->p[3].z = p->p[0].z;
for(j = 0; j < 4; j++){
p->col[j].argb.a = (Uint8)(0x80*njRandom());
p->col[j].argb.r = (Uint8)(0x80*njRandom());
p->col[j].argb.g = (Uint8)(0x80*njRandom());
p->col[j].argb.b = (Uint8)(0x80*njRandom());
}
njDrawPolygon3D(&p, 4, NJD_DRAW_NORMAL|NJD_FILL);
| Since this function draws in 3D, the view, screen, and matrix stack settings must be made before using it. |
NOTES
- The NJD_DRAW_NORMAL may be omitted when it is used in combination with other attributes.
