We propose a new algorithm for hardware-accelerated image-space reconstruction using pull-push interpolation and present an efficient GPU implementation. Compared to published image-space reconstruction approaches employing the pull-push interpolation, our method offers a significantly improved image quality because of the integration of elliptic boxfilters and support for deferred Phong shading. For large point-based models, our GPU implementation is capable of rendering more than 50M points per second including image-space reconstruction and deferred shading.Categories and Subject Descriptors (according to ACM CCS): I.3.3 [Computer Graphics]: Bitmap and framebuffer operations Display algorithms Viewing algorithms; I.3.7 [Computer Graphics]: Hidden line/surface removal
