Javascript – 3DS Max => ThreeJs. Export scene

You might want to check out lib3ds which will parse the 3ds binary format for you and give you access to all of the objects properties. I think Autodesk also has their own toolkit for doing this.

Try following code:-

 CIImage *inputImage = [[CIImage alloc] initWithImage:[UIImage imageNamed:@"old-country-rain.jpg"]];
CIFilter * controlsFilter = [CIFilter filterWithName:@"CIExposureAdjust"];
[controlsFilter setValue:inputImage forKey:kCIInputImageKey];
[controlsFilter setValue:[NSNumber numberWithFloat: 2.0f] forKey:@"inputEV"];
NSLog(@"%@",controlsFilter.attributes);
CIImage *displayImage = controlsFilter.outputImage;
UIImage *finalImage = [UIImage imageWithCIImage:displayImage];

CIContext *context = [CIContext contextWithOptions:nil];
if (displayImage == nil || finalImage == nil) {
    // We did not get output image. Let's display the original image itself.
    imageView.image = [UIImage imageNamed:@"old-country-rain.jpg"];
}else {
    // We got output image. Display it.
    imageView.image = [UIImage imageWithCGImage:[context createCGImage:displayImage fromRect:displayImage.extent]];
}
