# Geometric Property

The value of the specified geometric property (defined using ) of the currently-bound geometry.

## Parameter Types

**Geometric Property (float):**

|Input     |Type  |
                |----------|------|
                |`Geomprop`|String|
                |`Default` |Float |

|Output|Type |
                |------|-----|
                |`Out` |Float|

**Geometric Property (color4f):**

|Input     |Type         |
                |----------|-------------|
                |`Geomprop`|String       |
                |`Default` |Color4<Float>|

|Output|Type         |
                |------|-------------|
                |`Out` |Color4<Float>|

**Geometric Property (vector2f):**

|Input     |Type    |
                |----------|--------|
                |`Geomprop`|String  |
                |`Default` |Vector2f|

|Output|Type    |
                |------|--------|
                |`Out` |Vector2f|

**Geometric Property (color3f):**

|Input     |Type         |
                |----------|-------------|
                |`Geomprop`|String       |
                |`Default` |Color3<Float>|

|Output|Type         |
                |------|-------------|
                |`Out` |Color3<Float>|

**Geometric Property (vector3f):**

|Input     |Type    |
                |----------|--------|
                |`Geomprop`|String  |
                |`Default` |Vector3f|

|Output|Type    |
                |------|--------|
                |`Out` |Vector3f|

## Parameter descriptions

- `Geomprop`: The name of the geometric property to be read.
- `Default`: The value the node returns if it’s unable to read the geometric property.

## Discussion

The Geometric Property node attempts to return the value of the geometric property with the name defined by the `Geomprop` parameter. If that property doesn’t exist or there’s an error retrieving the property’s value, the node outputs the value of the `Default` parameter.

> Note: The type of this node must be the same as the type of the geometric property you’re attempting to reference.
