texture_mesh

Synopsis

map an image onto a surface, using UV coordinates generated from the surface XY coordinates

Input Ports

in_field	Mesh
texture	Field_Unif+Dim2+Space2+Byte
ui_parent	user interface parent object

Output Ports

out_fld	Mesh+Node_Data
out_obj	output renderable object

Description

texture_mesh uses the texture facility of the viewer to map an image onto a surface. The texture is applied using the (X,Y) coordinates of the mesh, so that the whole image is mapped to the (X,Y) range of the mesh. By default, the lower left of the texture is applied and x min , y min , and the upper right is applied at x max , y max . See the parameters for how to change this.

Input Ports

in_field

Field. The mesh to texture.

texture

Field_Unif+Dim2+Space2. The image to texture onto in_field.

ui_parent

A port to connect to a user interface object that contains the macro's widgets. By default, it is connected to the default user interface object in the application in which the macro is instanced. (This default connection is not drawn.)

Parameters

switch uv

UItoggle. Switch U and V (or X and Y) when generating the texture coordinates.

flip u

UItoggle. Flip U so that the texture is applied backwards in X.

flip v

UItoggle. Flip V so that the texture is applied backwards in Y.

u scale

UIslider. Scale U by this amount. The larger this value, the less space taken by the texture in X. Decreasing this value stretches the texture, increasing it compresses the texture.

v scale

UIslider. Scale V by this amount. The larger this value, the less space taken by the texture in Y. Decreasing this value stretches the texture, increasing it compresses the texture.

u shift

UIslider. Shift U by this amount. Positive shift shifts the texture to the left, negative shifts to the right.

v shift

UIslider. Scale V by this amount. Positive shift shifts the texture down, negative shifts up.

Output Ports

out_fld

Mesh+Node_Data. Contains the input mesh with the texture applied.

out_obj

Renderable object corresponding to out_fld.
