<\/p>\n<\/p>\n
Started making a mesh helper editor script. Should be useful to see the mesh details easily..<\/p>\n
Current features:<\/strong> TODO:<\/strong> —<\/p>\n
\n– Display selected object details (DrawGizmo<\/a>)
\n– Draw green boxes on vertex locations (Handles.DotCap<\/a>)
\n– Display vertex number and UV info (Handles.Label<\/a>)
\n– Label position is affected by the normals (so that overlapping vertice labes go bit different directions)
\n– Draw triangles with blue lines (Handles.DrawPolyLine<\/a>)
\n– Line positions are multiplied by 1.005f, so that the default wireframe doesnt block them..
\n– Display face normals (numbers and visual line)
\n– Hide back facing details (if wanted), works kind of.. (Access to editor camera position\/rotation\/etc: Camera.current<\/a> , not sure if there is other ways..)
\n– Use CustomEditor, instead of trying to modify every selected object (see image#4)
\n– Snap to closest vertices (using kdree<\/a>): Works, but positions in the tree are not yet updated after modifying vertices.. maybe it wouldnt need kdree at all.
\n– Vertex position editor : first version works, just need to add mesh update while dragging the vertices<\/p>\n
\n– Draw handles with vertex colors (if exists)
\n– Vertex color editor
\n– Total vertex count
\n– Different color\/style for the label texts
\n– Pivot position editor
\n– Show original mesh outlines
\n– Undo functionality (i guess its done with this: Undo.SetSnapshotTarget<\/a>)
\n– UV value editor
\n– normal value editor
\n– Flip normals tool
\n– Export Tools: Export as script (like mMesh<\/a>)
\n– Save modified mesh
\n– Button to “Reset mesh to original”
\n– Show vertex distance from startpoint when dragging
\n– Show vertex position (local and world) when dragging
\n– Flip \/ Mirror, flips all mesh vertices
\n– Maybe later: Removing \/ adding vertices?
\n– Maybe later: Optimize mesh? Smoothen\/relax vertices?
\n– DX11 stuff?
\n–<\/p>\n
\nSNIPPETS:<\/strong><\/p>\n\r\n\/\/ calculate triangle centroid (center of 3 points)\r\n\/\/ http:\/\/math.tutorvista.com\/geometry\/centroid.html\r\nVector3 centroid = (vertexpos1+vertexpos2+vertexpos3)\/3;\r\n\r\n\/\/ get mouse world position (without raycasting), inside void OnSceneGUI()..\r\n\/\/huh that took couple hours to get it working..unity docs ><, althought it doesnt work in most cases still..\r\nRay r = HandleUtility.GUIPointToWorldRay(Event.current.mousePosition);\r\nVector3 worldPos = r.GetPoint(Vector3.Distance(r.origin,targetObj.position));\r\n<\/pre>\n
