Based on research results in 2D applications, we believe that two-handed input provides the potential for creating more efficient and more fluid interfaces, especially for tasks that are context-sensitive or that have many degrees of freedom. These tasks appear frequently in 3D applications and are commonly broken down into a series of sequential operations, each controlling fewer degrees of freedom – even though this may dramatically change the character of the task. However, two-handed interaction, in theory, makes it possible to perform the same tasks using half the number of sequential steps since two previously sequential operations can be performed simultaneously. In addition, many forms of two-handed interaction may be simpler to use and to understand since they correspond to common interactions in the physicat world. It is significant when tasks that need to be broken down into two sequential single-cursor steps, can be performed as a single fluid operation using two cursors.

Typically, visibility determination is performed using the z-buffer algorithm. As this algorithm must examine every triangle in the input scene, z-buffering can consume a significant fraction of graphics processing, especially on architectures that have a low performance or software z-buffer. One way to avoid needlessly processing invisible portions of the scene is to use an occlusion culling algorithm to discard invisible polygons early in the graphics pipeline. In this paper, we exploit the presence of large occluders in urban and architectural models to design a real-time occlusion culling algorithm. Our algorithm has the following features: it is conservative, i.e., it overestimates the set of visible polygons; it exploits spatial coherence by using a hierarchical data structure; and it exploits temporal coherence by reusing visibility information computed for previous viewpoints. The new algorithm significantly accelerates rendering of several complex test models.

We provide recttrsive reflections and refractions through the use of secondary viewpoints and projective image mapping. We extend the traditional use of shadow volumes to provide global direct illumination effects which fit into our recursive viewpoint paradiim. Hardware surface shading is fit to a physicallybaaed BRDF to provide a better local model, and the framework permits incorporation of indirect illumination as well. Furthermore, material transmittance is approximated using an extension to projective textures. Together, these techniques provide a platform for producing realistic images in highly dynamic environments. While most appropriate for scenes which specular components contribute largely to the secondary illumination, the integration of MPR with indirect racliosity solutions also provides a dynamic solution for highly diffuse environments. These techniques are immediately applicable to areas such as walkthroughs, animation, and interactive dynamic environments to produce more realistic images in near real-time.","PeriodicalId":308950,"journal":{"name":"Proceedings of the 1997 symposium on Interactive 3D graphics","volume":"153 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134397644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
