Virtual reality is what has the market today. Everywhere you turn, you are sure to see one or two virtual reality gaming centers or VR headsets, etc. technology has improved to such an extent that people can experience this virtual reality even in their homes, by just using their phones and the specific VR headsets for them.
HDR – High Dynamic Range rendering is what makes this VR possible. HDR increases the realistic feel of the images and the videos, as a result, the user is immersed more into this virtual world before he loses himself to it and forgets the real world. After the game is done, the player is left with such an experience that is bound to stay fresh in his mind for quite some time.
Here are 3 important things one must know about HDR if they are planning to use this in their profession:
- Lighting is extremely important. As long as the light sources used are good and close to real-time lighting, the output will be more realistic. I used a melbourne 3d company and my project video looks like it has been shot in real time. This is because they paid attention to the color space and adjusted the light sources accordingly.
- The natural environment has a number of textures and materials and these have to be incorporated into the 3D render as well. If the render is free of such textures or materials, one can easily make out the graphics involved, thus reducing the effectiveness of the 3D rendering.
- Checking you final 3D images against a number of state of the art tone mapping operators will help you achieve a result that is very close to reality. The more realistic it looks, the more successful your output it. Tone mapping operators help in retaining the perceptual reality of the human visual system, thus making it more realistic.
