Unigine::FieldShoreline Class

Header:	#include <UnigineFields.h>
Inherits:	Field

Sort by:

List of functions:

This class is used to create and modify a field shoreline. The field is applied to global water and helps to create swashes near the shores and applies the wetness effect on objects near the shoreline.

Notice

A field shoreline object will affect water only if the FieldShoreline interaction option is enabled on the States tab of the water_global_base material.

Creating a Shoreline Field

NoticeWhen creating a FieldShoreline object you should specify a shoreline texture for as this object doesn't have any default texture.

Source code (C++)

// create a new instance of the FieldShoreline class and set its transformation
FieldShorelinePtr shoreline = FieldShoreline::create();
shoreline->setTransform(Mat4(1));
// set the size of the field 
shoreline->setSize(vec3(4096.0f, 4096.0f, 512.0f));
// set the path to the shoreline texture
shoreline->setTexturePath("unigine_project/textures/shorelines/shoreline_0.dds");

To add the FieldShoreline object to UnigineEditor, add the following code:

Source code (C++)

// release class ownership of the FieldShoreline
shoreline->release();
// add the FieldShoreline to the list of editor nodes
Editor *editor = Editor::get();
editor->addNode(shoreline->getNode());

FieldShoreline Class

Members

static FieldShorelinePtr create()

Default constructor. Creates a FieldShoreline instance with the default size vec3(512.0f, 512.0f, 512.0f).

NoticeBy default, a shoreline texture is empty. Specify it after creating the FieldShoreline by using an appropriate function.

Ptr<FieldShoreline> cast(const Ptr<Node> & node)

Casts the FieldShoreline out of the Node instance.

Arguments

const Ptr<Node> & node - Node smart pointer.

Return value

FieldShoreline smart pointer.

Ptr<FieldShoreline> cast(const Ptr<Field> & base)

Casts the FieldShoreline out of the Field instance.

Arguments

const Ptr<Field> & base - Field smart pointer.

Return value

FieldShoreline smart pointer.

void setTexture(const Ptr<Texture> & texture)

Sets the given texture from the Texture instance for the FieldShoreline.

Arguments

const Ptr<Texture> & texture - Texture instance.

Ptr<Texture> getTexture()

Returns the shoreline texture (from GPU) and saves it into the given Texture instance.

Return value

Shoreline texture.

int setTextureImage(const Ptr<Image> & image)

Sets the given image as the shoreline texture of the FieldShoreline

Arguments

const Ptr<Image> & image - Image instance with a shoreline texture for the FieldShoreline.

int getTextureImage(const Ptr<Image> & image)

Grabs the texture for the FieldShoreline (already loaded to GPU) and saves it into the given Image instance.

Arguments

const Ptr<Image> & image - Image instance into which the texture will be saved.

Return value

1 if the texture has been grabbed successfully; otherwise, 0.

int setTexturePath(const char * name)

Sets the path to the FieldShoreline's shoreline texture.

Arguments

const char * name - Path to the shoreline texture.

Return value

1 if the path to the shoreline texture is set successfully; otherwise, 0.

const char * getTexturePath()

Returns the path to the FieldShoreline's shoreline texture.

Return value

Path to the shoreline texture.

void setSize(const Math::vec3 & size)

Sets the vec3 size vector of the FieldShoreline.

The default value is (512.0f, 512.0f, 512.0f).

Arguments

const Math::vec3 & size - Size vector (x,y,z), where:
- x value is length of the FieldShoreline along X axis (in units),
- y value is length of the FieldShoreline along Y axis (in units),
- z value is length of the FieldShoreline along Z axis (in units).

Math::vec3 getSize()

Returns the vec3 size vector of the FieldShoreline.

The default value is (512.0f, 512.0f, 512.0f).

Return value

Size vector (x,y,z), where:

x value is length of the FieldShoreline along X axis (in units),
y value is length of the FieldShoreline along Y axis (in units),
z value is length of the FieldShoreline along Z axis (in units).

int createShorelineDistanceField(const Ptr<Image> & image, int shoreline_radius, int blur_radius, int downsample_resolution)

Creates a shoreline distance field with the specified parameters and put it into the Image file.

Source code

float shoreline_radius = 64;
int blur_radius = 8;
int downsample_resolution = 128;
Image distance_field = new Image();
field.createShorelineDistanceField(distance_field,shoreline_radius,shoreline_blur,downsample_resolution)

Arguments

const Ptr<Image> & image - Pointer to the Image file.
int shoreline_radius - Radius of the shoreline.
int blur_radius - Radius of the blurred area.
int downsample_resolution - Shoreline resolution.

Return value

1 if the field was created successfully; otherwise, 0.

int type()

Returns the type of the object.

Return value

FieldShoreline type identifier.
