摘要: PDMS提供了平台梯子建模功能,程序比较通用,没有根据国内公司相关标准建模出图,不能满足设备专业的出图汇料要求。通常是管道专业在PDMS中把结构、设备及其平台梯子建模,再提相关委托和结构、设备专业进行协同设计。因为管道专业建的平台、梯子不能按结构、设备专业要求进行出图,所以导致设备专业不愿意进入PDMS。 开发程序对设备专业的平台梯子进行精确建模,并且在精确模型的基础上自动出图、汇料。这样就可以使设备专业设计人员愿意进入PDMS进行设计,一键出图汇料。对设备平台、支架和梯子进行建模,可以在模型中避免与管道等的碰撞,提高设计质量和效率。 通过程序开发,在输入尽量少的参数下对设备平台梯子快速建模。对于建好的模型,一键自动出图。阅读全文

摘要: Abstract. Bounding Volume Hierarchy(BVH) organizes geometric objects in the tree based on spatial relationships. Each node in the tree contains an axis-aligned bounding box of all the objects below it. Bounding volume hierarchies are used in many algorithms to support efficient operations on the sets of geometric objects, such as collision detection, ray-tracing, searching of nearest objects, and view frustum culling. The paper focus on the usage of BVH on TopoDS_Shape, and its application. K阅读全文
