Primitives Example

MorphoNet has a system named primitive that allow you to upload a mesh as a primitive, and instantiate this primitive instead of instantiating multiple times the same mesh. This is very efficient for simulation

import morphonet

mn_login="user"
mn_password="password"
mn=morphonet.Net(mn_login,mn_password)

Let’s create a dataset with only 1 time step

Parameters

name : (string) name of the new dataset

minTime : (int) begin time point

maxTime : (int) end time point , here the same than begin because we don’t have any time properties

mn.create_dataset("api_test_primitive",minTime=0,maxTime=0)

Than we will load into memory the primitives source we want to upload

prim1 = mn.read_mesh("DATASET/Multiple_Objs/obj502.obj")
prim2 = mn.read_mesh("DATASET/Multiple_Objs/obj505.obj")

Than we can upload the mesh that will be the primitive in the dataset

Parameters

name : (string) Name of the primitive

obj : (bytes) 3d data of the primitive

mn.upload_primitive("object1",prim1)
mn.upload_primitive("object2",prim2)

Than we can upload the mesh for the time point that use the primitives. You can check on MorphoNet format help to create a mesh file with the correct format to use primitives

mesh1 = mn.read_mesh("DATASET/Multiple_Objs/obj506.obj")
mn.upload_mesh_with_primitive_at(0,mesh1)

If a primitive is not used you can delete a primitive by it’s name for the dataset

Parameters

name : (string) name of the primitive to delete

mn.delete_primitive("object1")

Or you can delete all primitive of current dataset

mn.delete_primitives()
