mindelec.geometry.CSGDifference
- class mindelec.geometry.CSGDifference(geom1, geom2, sampling_config=None)[源代码]
几何差异的CSG类。
- 参数:
geom1 (Geometry) - 几何体对象。
geom2 (Geometry) - 要从 geom1 中减去的几何体对象。
sampling_config (SamplingConfig) - 采样配置。默认值:None。
- 支持平台:
Ascend
样例:
>>> from easydict import EasyDict as edict >>> from mindelec.geometry import create_config_from_edict, Disk, Rectangle, CSGDifference >>> sampling_config_csg = edict({ ... 'domain': edict({ ... 'random_sampling': True, ... 'size': 1000, ... 'sampler': 'uniform' ... }), ... 'BC': edict({ ... 'random_sampling': True, ... 'size': 200, ... 'sampler': 'uniform', ... 'with_normal': True, ... }), ... }) >>> disk = Disk("disk", (1.2, 0.5), 0.8) >>> rect = Rectangle("rect", (-1.0, 0), (1, 1)) >>> diff = CSGDifference(rect, disk) >>> diff.set_sampling_config(create_config_from_edict(sampling_config_csg)) >>> domain = diff.sampling(geom_type="domain") >>> bc, bc_normal = diff.sampling(geom_type="bc") >>> print(domain.shape) (1000, 2)
