Unigine.FieldHeight Class
| Inherits from: | Field |
This class is used to create and modify a field height. The field is applied to global water and specifies areas where height of waves should be changed.
Notice
The maximum number of the rendered FieldHeight objects per frame/bit mask is 8.
Creating a Height Field
Notice
When creating a FieldHeight object you should specify a heightmap texture for it as this object doesn't have any default texture.
Source code (C#)
// create a new instance of the FieldHeight class and set its transformation
FieldHeight height = new FieldHeight();
height.setTransform(Mat4(1));
// set the size of the field
height.setSize(vec3(4096.0f, 4096.0f, 512.0f));
// set the heightmap texture
height.setTexturePath("unigine_project/textures/fh_static.png");See also#

FieldHeight Class
Properties
Texture Texture#
The heightmap texture (from gpu) and saves it into the given texture instance.
string TexturePath#
The path to the fieldheight's heightmap texture.
int BlendMode#
The current field height blending mode.
Notice
Attenuation parameter is interpreted depending on the selected blending mode:
- is used as a mulpiplier for the additive mode
- lerp(1.0f, value, attenuation) is used for the multiplicative mode
int Order#
The current field height rendering order.
Notice
This parameter is used to properly apply fields with mixed blend modes.
float Power#
The fieldheight's power value. the power is a multiplier for loaded heightmap texture values.
float Attenuation#
The fieldheight's attenuation factor value. the attenuation factor indicates the rate of filedheight influence attenuation from the center of the object to its edges.
vec3 Size#
The vec3 size vector of the fieldheight's object.
Members
FieldHeight ( ) #
The default constructor. Creates a FieldHeight instance with the default size vec3(1.0f, 1.0f, 1.0f).Notice
By default, a heightmap texture is empty. Specify it after creating the FieldHeight by using an appropriate function.
int SetTextureImage ( Image image ) #
Sets the given image as the heightmap texture of the FieldHeight.Arguments
- Image image - Image instance with heightmap for FieldHeight.
Return value
1 if the texture is set successfully; otherwise, 0.int GetTextureImage ( Image image ) #
Grabs the texture for the FieldHeight (already loaded to GPU) and saves it into the given Image instance.Arguments
- Image image - Image instance into which the texture will be saved.
Return value
1 if the texture has been grabbed successfully; otherwise, 0.static int type ( ) #
Returns the type of the object.Return value
FieldHeight type identifier.Last update:
