API changes
Added class Aspose.ThreeD.Shading.TextureSlot
This exposed the internal texture slots in materials, in order to access all available texture slots from a material, use foreach statement:
var mat = new PbrMaterial();
foreach(var textureSlot in mat)
{
Console.WriteLine(textureSlot.SlotName);
Console.WriteLine(textureSlot.Texture);
}Added class Aspose.ThreeD.TrialException
From 21.2, when the unlicensed usage reached the license restriction, a TrialException will be thrown to notify the license restriction, and how to apply for a temporary license.
You can simply ignore this by surround try/catch block on the Save/Open operation, or turn this exception off by:
TrialException.SuppressTrialException = true;Turn this message off will not lift the restrictions(Like extra nodes are ignored by exporter/importer).
In order to get all full feature, please request a temporary license or buy a full feature license.
Added methods to Aspose.ThreeD.Entities.TriMesh
public Aspose.ThreeD.Utilities.Vector4 ReadVector4(int idx, Aspose.ThreeD.Utilities.VertexField field);
public Aspose.ThreeD.Utilities.FVector4 ReadFVector4(int idx, Aspose.ThreeD.Utilities.VertexField field);
public Aspose.ThreeD.Utilities.Vector3 ReadVector3(int idx, Aspose.ThreeD.Utilities.VertexField field);
public Aspose.ThreeD.Utilities.FVector3 ReadFVector3(int idx, Aspose.ThreeD.Utilities.VertexField field);
public Aspose.ThreeD.Utilities.Vector2 ReadVector2(int idx, Aspose.ThreeD.Utilities.VertexField field);
public Aspose.ThreeD.Utilities.FVector2 ReadFVector2(int idx, Aspose.ThreeD.Utilities.VertexField field);
public double ReadDouble(int idx, Aspose.ThreeD.Utilities.VertexField field);
public float ReadFloat(int idx, Aspose.ThreeD.Utilities.VertexField field);These methods allow you to read vertex’s field without allocating extra memory, the traditional way of accessing vertex from TriMesh actually generates a lot of temporary object, these can provide fast and low-memory footprint access.
Scene s = new Scene(@"test.STL");
var mesh = (Mesh)s.RootNode.ChildNodes[0].Entity;
//Create a new VertexDeclaration, so the TriMesh we constructed later will use this memory layout.
var vd = new VertexDeclaration();
var pos = vd.AddField(VertexFieldDataType.FVector3, VertexFieldSemantic.Position);
var normal = vd.AddField(VertexFieldDataType.FVector3, VertexFieldSemantic.Normal);
var uv = vd.AddField(VertexFieldDataType.FVector2, VertexFieldSemantic.UV);
//create a TriMesh instance from Mesh instance with manually specified vertex declaration
var m = TriMesh.FromMesh(vd, mesh);
for(int i = 0; i < m.VerticesCount; i++)
{
//access each field
var v_pos = m.ReadFVector3(i, pos);
var v_normal = m.ReadFVector3(i, normal);
var v_uv = m.ReadFVector3(i, uv);
Console.WriteLine($"({v_pos}), ({v_uv}), ({v_normal})");
}Added new file format in Aspose.ThreeD.FileFormat
/// <summary>
/// Compressed Universal Scene Description
/// </summary>
public static readonly FileFormat USDZ;Aspose.3D 21.2 can load USDZ format now.
