Embodiment Construction
[0062] The invention provides a CPU-GPU coordinated additive manufacturing parallel filling method, which adopts the method of parallelizing the algorithm, utilizes the powerful parallel computing capability of the GPU, and combines the super multi-task coordination and comprehensive scheduling capability of the multi-core CPU. The scan line filling algorithm is improved, making full use of the computing resources of the hardware platform, and optimizing and accelerating the most time-consuming intersection sorting calculation process through the C++ multi-threading library, CUDA library, etc.
[0063] The concrete steps of the present invention are:
[0064] Step 1. Data preprocessing
[0065] After the 3D model of the part to be additively manufactured is layered, the 3D model is divided into several layers according to the height from low to high, the number of layers is set to Layers, and Layers is a positive integer. First of all, it is necessary to calculate the task am...
