Neural Rendering for Full-Dive VR

2025-09-01

Neural rendering achieves photorealism at VR frame rates. Combined with eye-tracking enables indistinguishable-from-reality VR.

NeRF Implementation

\\\`python class NeRF(nn.Module): def forward(self, position, direction): """ Input: 3D position + viewing direction Output: RGB color + density """ x = self.mlp(torch.cat([position, direction])) rgb = torch.sigmoid(x[:3]) density = F.relu(x[3]) return rgb, density

Render novel views from any angle

def renderimage(nerf, camerapose): rays = generaterays(camerapose) colors = [] for ray in rays: color = volumetric_rendering(nerf, ray) colors.append(color) return colors \\\` Frame rate: 90+ fps needed for VR Related: VR Addiction Pandemic (2054)
