I have made a little Demo of the OpenGL NXC 3d functions controlled by a wii nunchuk:

Can you post the program?
Thanks, and have a nice day,

Re: NXC 3D Engine and a Wii Nunchuck
Yes. But I will make tomorow a "clean copy":
Code: Select all
byte CMDNunchukInit[] = {0xA4, 0x40, 0x00};
byte CMDNunchukWrite[] = {0xA4, 0x00};
byte CMDNunchukRead[] = {0xA4};
byte nbytes;
byte outbuf[];
// port is the NXT port
// i2c_cmd is the nunchuk internal address register
// at i2c_cmd=0...5 are 6 Byte of sensor values
// at i2c_cmd=0x20 ... 0x2F you get 16 Byte of calibration data
sub NunchukGetParamter(byte port, byte i2c_cmd)
{
// Initialize the Nunchuk
SetSensorLowspeed(port);
LowspeedWrite(port, 0, CMDNunchukInit); //ask for 0 bytes
while(LowspeedStatus(port, nbytes)>0);
// Wait(1) is needless, the NXT command interpreter delays next i2c access 3ms
CMDNunchukWrite[1] =i2c_cmd; //at 0x00: 6 Bytes of sensor values
LowspeedWrite(port, 0, CMDNunchukWrite); // write Nunchuk register address
while(LowspeedStatus(port, nbytes)>0);
byte count = 6;
LowspeedWrite(port, count, CMDNunchukRead); //ask for count bytes
while(LowspeedStatus(port, nbytes)>0);
if(nbytes == count){
LowspeedRead(port, count, outbuf) //read data from buffer
for(int i=0; i<count; i++ ){
outbuf[i]=(outbuf[i]^0x17) + 0x17;
}
}
else {
ArrayInit(outbuf,0,0); //error
}
}
int angleX, angleY;
task main()
{
// Initialize the 3D engine...
glInit();
// Create a box, this is the first object which will be object id 0...
glBox(GL_POLYGON, 10, 20, 30);
// Create a box, this is the second object which will be object id 1...
glBox(GL_POLYGON, 30,40,50);
//glSetAngleX(0);//100
//glSetAngleY(0);//125
angleX = 0;
angleY = 0;
while (true)
{
/*
// Setup for rendering...
glBeginRender();
// Call the object with id 0...
glCallObject(0);
glObjectAction(0, GL_ROTATE_X, angleX);
// Call the object with id 1...
glCallObject(1);
glObjectAction(1, GL_ROTATE_Y, angleY);
// Finish, clear the screen, rotate and render the called objects...
glFinishRender();
*/
NunchukGetParamter(S1, 0x00);
if (ArrayLen(outbuf)==6)
{
glBeginRender();
glCallObject(0);
//NumOut(0,0,(outbuf[0]),false);
//NumOut(0,10,(outbuf[1]),false);
glObjectAction(0, GL_ROTATE_Y, (225-outbuf[0]));
glObjectAction(0, GL_ROTATE_X, (outbuf[1]));
glCallObject(1);
glObjectAction(1, GL_ROTATE_Y, ((225-outbuf[2])*3));
glObjectAction(1, GL_ROTATE_X, (outbuf[3])*3);
glFinishRender();
//Wait(1000);
}
}
}

Nice
I tried the NXC 3D engine, the ease of use is quite impressive!

Re: NXC 3D Engine and a Wii Nunchuck
Awsome!!!! i like 3D!!!!
Oh, and i would like it if you made a small program like that, but one box and uses the Enter, Left, Right, and Exit button.

Have you seen my NXC GL post? Also, the documentary might help. (Rightclick a command in BricxCC, then select 'help topics'.)
