[英]How to load 3d model with .obj and .mtl file in Vuforia Augmented Reality iOS sdk
[英]How to Load, render and display 3d model of obj format created by maya or blender in iphone with textures as png or jpg?
嗨,我知道網上有很多wavefrontobj解析器可以加載.obj模型,但是大多數都沒有紋理加載,因此我需要知道如何加載TEXTURES(.png和.jpg)。 我也編寫了用於縮放3d模型並與其進行交互的代碼,但是它不起作用。 因此,誰能幫助我解決這個問題。 具有上述所有功能的任何示例應用程序將受到高度贊賞。
提前致謝..
縮放代碼:
- (void)scale:(id)sender
{
if([(UIPinchGestureRecognizer*)sender state] == UIGestureRecognizerStateEnded)
{
lastScale = 1.0;
return;
}
CGFloat prevZoomValue = zoomValue;
CGFloat scale = (1.0 - (lastScale - [(UIPinchGestureRecognizer*)sender scale]))/10;
if ([(UIPinchGestureRecognizer*)sender scale] < 1)
{
//user is zooming in
// range 1.0 to 0.0
zoomValue -= scale;
}
else
{
//user is zooming out
// range > 1.0
zoomValue += scale/10;
}
// if zoom value is not in the range then restore last value
if (!(zoomValue < -0.1 && zoomValue > -10.0))
{
zoomValue = prevZoomValue;
lastScale = [(UIPinchGestureRecognizer*)sender scale];
}
}
互動代碼:
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
// NSMutableSet *currentTouches = [[[event touchesForView:self] mutableCopy] autorelease];
// [currentTouches minusSet:touches];
secondsInterval = CFAbsoluteTimeGetCurrent();
//longPressTimer = [NSTimer scheduledTimerWithTimeInterval:0.01 target:self selector:@selector(startLongPressCounter) userInfo:nil repeats:YES];
// New touches are not yet included in the current touches for the view
lastMovementPosition = [[touches anyObject] locationInView:self];
rotateX = endMovementPosition.x;
rotateY = endMovementPosition.y;
}
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
idleRotate = FALSE;
CGPoint currentMovementPosition = [[touches anyObject] locationInView:self];
NSLog(@"touchesMoved");
rotateX = (lastMovementPosition.x - currentMovementPosition.x);
rotateY = (lastMovementPosition.y - currentMovementPosition.y);
//[self renderByRotatingAroundX:(lastMovementPosition.x - currentMovementPosition.x) rotatingAroundY:(lastMovementPosition.y - currentMovementPosition.y)];
lastMovementPosition = currentMovementPosition;
}
NSString *path = [[NSBundle mainBundle] pathForResource:@"cubeimage" ofType:@"jpg"];
OpenGLTexture3D *newTexture = [[OpenGLTexture3D alloc] initWithFilename:path width:512 height:512];
self.texture = newTexture;
[newTexture release];
