GetShaderInputType (Material)

Introduced

5.0

Description

Returns the shader input type for the specified parameter. If the parameter cannot be connected to another shader GetShaderInputType returns siUnknownInputType.

Scripting Syntax

Material.GetShaderInputType( ParameterScriptName )

C# Syntax

siShaderParameterType Material.GetShaderInputType( String Parametername );

Parameters

Return Value

siShaderParameterType

Examples

JScript Example

// Create an object with a texture shader
var root = Application.ActiveProject.ActiveScene.Root;
var model = root.AddModel();
model.Name = "MyModel";
var object = model.AddGeometry( "Sphere", "MeshSurface" );

BlendInPresets( "Image", object, 1, false );
CreateProjection( object, siTxtSpherical, siTxtDefaultSpherical, "TxtSupport", "TxtProjection" );

var filename = Application.InstallationPath( siFactoryPath ) + 
   "\\Data\\XSI_SAMPLES\\Pictures\\xsilogo.jpg";

var imageclip = CreateImageClip( filename, "XSILogo" );

// Set up the texture space on the texture shader
var mat = object.Material;
var textureshader = null;

// Different ways to get the texture shader:
// Method 1
textureshader = object.Material.CurrentTexture;

// Method 2
var shaders = mat.FindShaders(siShaderFilter);
textureshader = shaders("Image");

// Method 3
textureshader = mat.Shaders("Phong").Shaders("diffuse_blend").Shaders("Image");

// Set the texturespace parameters
textureshader.Parameters("tspace_id").Value = "TxtProjection";
textureshader.Parameters("tex").Connect(imageclip);

// List the names and input types of all parameters that support shader connections
var eParams = new Enumerator(mat.Parameters);

for ( ; !eParams.atEnd(); eParams.moveNext() )
{
   var param = eParams.Item();

   if (param.capabilities & siTexturable)
