Houdini: 頂点参照
・ point("/obj/geo1/facet1", 3, "P", 0)
頂点 （指定のノード場所, 頂点番号, 指定形式（上記の場合、vertex）, X軸）
・point("/obj/geo1/facet1", 3, "N", 2)
頂点 （指定のノード場所, 頂点番号, 指定形式（上記の場合、normal）, Z軸）
・英語での説明
float point (string surface_node, float point_number, string attribute, float index)
string surface_node: sopのpath
string attribute: アトリビュートの名前（string型）Houdiniのローカルルール。
ex.) P, Pw, N, Cd など。
float index: データタイプを表記するアトリビュート。Houdiniのローカルルール。
ex.) 0, 0-3, 0-4 などをアトリビュートのデータタイプによって使用する。
0指定は、色、0-3はベクター、0-4はベクター４．
詳細は以下。
float point (string surface_node, float point_number, string attribute, float index)
REPLACED BY
hou.Geometry.iterPoints()
hou.Point.attribValue()
Returns the value of a point attribute.
<surface_node> is a path to a surface node, for example
"/obj/geo1/grid1". <point_number> is the point number to read the
attribute from.
<attribute> is the name of the attribute (for example, Cd for diffuse
color). Two special attributes exist: P and Pw which represent the
position of the point in space (Pw allows you to access the W component
of the position).
<index> is the component number (0, 0 to 3, or 0-4, depending on the
datatype of the attribute) to read if the attribute is a vector or
vector4. For floats, the index argument is ignored (just use 0). For
example, for a color value, 0 means red, 1 means green, and 2 means
blue. To read the all three (red, green, and blue) components, you would
need to call the function three times with 0, 1, and 2 as the values for
<index>.
This function will interpolate between point values if the point number
is fractional, such as 3.35
EXAMPLES
point("/obj/geo1/facet1", 3, "P", 0)
Returns the X component of point 3 of the facet1 surface node in
geo1.
point("/obj/geo1/facet1", 3, "N", 2)
Returns the Z component of the normal attribute of point 3 in the
facet1 surface node of object geo1.
