Hi there,
Here is the translated Dot3D and Line3D from Cloggy's d3dfunc.dll:
d3dfunc.h :
void InitD3DFunc();

void d3d_SetView ( int nLeft, int nTop, int nRight, int nBottom);

And sample code:
#include "DarkSDK.h"
#include "d3dfunc.h"
void DarkSDK(void) {
float ca=0;
float cx=0;
float cz=0;
float x1=0;
float y1=0;
float z1=0;
float x2=0;
float y2=0;
float z2=0;
float zpos=50;
float zmove=0;
int x=0;
int y=0;
dbSyncOn();
dbSyncRate(90);
InitD3DFunc();
for (int i=1 ; i<21 ;i++)
{
dbMakeObjectSphere (i+100,1);
//remove to see objects
dbHideObject(i+100);
}
while (LoopSDK())
{
if (dbEscapeKey())
return;
cx=dbCos(ca)*zpos;
cz=dbSin(ca)*zpos;
dbPositionCamera (cx,2,cz);
dbPointCamera (0,0,0);
ca+=.1;
dbRandomize (1);
x1=dbRnd(20)-5;
y1=dbRnd(20)-5;
z1=dbRnd(20)-5;
for (int i=1 ; i<21 ; i++)
{
x2=dbRnd(20)-5;
y2=dbRnd(20)-5;
z2=dbRnd(20)-5;
dbPositionObject (i+100,x1,y1,z1);
//red points
d3d_dot3D (x1, y1, z1, 1, 255, 0, 0, 255 );
//change to "0" the "1" for disabling zenable of the 3d lines
d3d_line3D (x1, y1, z1, x2, y2, z2, 1, dbRnd(255), dbRnd(255), dbRnd(255), dbRnd(100) );
x1=x2;
y1=y2;
z1=z2;
}
if (zpos>=50) zmove=-.01;
if (zpos<=-50) zmove=.01;
zpos=zpos+zmove;
dbSync();
}
}
The code works fine at the example. 3D dots appear in red.
However, I have a couple of issues and if somebody has any clue, I would be grateful. I inserted the functions in a big project so I don't know exactly what's wrong, but:
1 - 3D Lines do not obey ZENABLED flag, they appear over any 3d object.
2 - 3D Dots do not appear as dots, but as squared sprites.
I'm stuck finding out the reasons why.
