Detailed Description

The GeoActivity is a an Android Activity that includes a GeoFragment in order to control the camera and map process.

At its creation it open the camera and setup all its parameters and the internal variables of the system.

It exposes the same methods of the GeoFragment to manage the geo process

Extending this activity makes possible to override its methods from IRecognitionListener and IArGeoListener.

Returns if the Pikkart-AR SDK is currently tracking a marker.

◆ getCurrentMarker()

static Marker com.pikkart.ar.geo.GeoActivity.getCurrentMarker ( )

static

Returns the currently tracked marker.

Returns: A Marker object if the Pikkart-AR SDK is currently tracking a marker, null otherwise.

◆ getCurrentProjectionMatrix()

static float [] com.pikkart.ar.geo.GeoActivity.getCurrentModelViewMatrix ( )

static

Returns the current modelview matrix and make it available for rendering purpose.

Returns: A row-major array of 16 float representing a 4x4 matrix.

◆ renderCamera()

static void com.pikkart.ar.geo.GeoActivity.renderCamera	(	int	viewportWidth,
		int	viewportHeight,
		int	angle
	)

static

Create a texture and render the current camera frame.

This method has to be called inside an OpenGL context and called whenever is necessary to update the current image.

It manages automatically creation, update and deletion of the texture.

Please refers to the tutorial if you want a better understanding of how to use this method.

Parameters

viewportWidth	The width in pixels of the rendered camera image.
viewportHeight	The height in pixels of the rendered camera image.
angle	The current angle of rotation of the device.

◆ enableTorch()

boolean com.pikkart.ar.geo.GeoActivity.enableTorch ( )

Turn on the torch of the device.

Returns: true if the device provides a torch, false otherwise

◆ disableTorch()

boolean com.pikkart.ar.geo.GeoActivity.disableTorch ( )

Turn off the torch of the device.

Returns: true if the device provides a torch, false otherwise

◆ setFocusMode()

void com.pikkart.ar.geo.GeoActivity.setFocusMode ( String mode )

Set the selected focus mode for the camera if available for the device.

Currently supported focus modes are FOCUS_MODE_MACRO, FOCUS_MODE_INFINITY, FOCUS_MODE_CONTINUOUS_VIDEO, FOCUS_MODE_AUTO included into Camera.Parameters class of the Android SDK.

Parameters

mode	A string representing a focus mode included in Camera.Parameters.
