Examples with Tile org.orekit.models.earth.tessellation.Tile used on opensource projects

Example 1 with Tile

use of org.orekit.models.earth.tessellation.Tile in project Orekit by CS-SI.

the class TileTest method testCenteredSquare.

@Test
public void testCenteredSquare() {
    double angle = 0.25;
    GeodeticPoint v0 = new GeodeticPoint(-angle, -angle, 100.0);
    GeodeticPoint v1 = new GeodeticPoint(-angle, +angle, 100.0);
    GeodeticPoint v2 = new GeodeticPoint(+angle, -angle, 100.0);
    GeodeticPoint v3 = new GeodeticPoint(+angle, +angle, 100.0);
    Tile tile = new Tile(v0, v1, v2, v3);
    assertThat(tile.getVertices()[0], geodeticPointCloseTo(v0, 1.0e-9));
    assertThat(tile.getVertices()[1], geodeticPointCloseTo(v1, 1.0e-9));
    assertThat(tile.getVertices()[2], geodeticPointCloseTo(v2, 1.0e-9));
    assertThat(tile.getVertices()[3], geodeticPointCloseTo(v3, 1.0e-9));
    assertThat(tile.getVertices()[3], geodeticPointCloseTo(v3, 1.0e-9));
    assertThat(tile.getInterpolatedPoint(0, 0), geodeticPointCloseTo(v0, 1.0e-9));
    assertThat(tile.getInterpolatedPoint(1, 0), geodeticPointCloseTo(v1, 1.0e-9));
    assertThat(tile.getInterpolatedPoint(1, 1), geodeticPointCloseTo(v2, 1.0e-9));
    assertThat(tile.getInterpolatedPoint(0, 1), geodeticPointCloseTo(v3, 1.0e-9));
    assertThat(tile.getCenter(), geodeticPointCloseTo(new GeodeticPoint(0.0, 0.0, 100.0), 1.0e-9));
}

Example 2 with Tile

use of org.orekit.models.earth.tessellation.Tile in project Orekit by CS-SI.

    Tile tile = new Tile(v0, v1, v2, v3);
    assertThat(tile.getVertices()[0], geodeticPointCloseTo(v0, 1.0e-9));
    assertThat(tile.getVertices()[1], geodeticPointCloseTo(v1, 1.0e-9));
    assertThat(tile.getVertices()[2], geodeticPointCloseTo(v2, 1.0e-9));
    assertThat(tile.getVertices()[3], geodeticPointCloseTo(v3, 1.0e-9));
    assertThat(tile.getVertices()[3], geodeticPointCloseTo(v3, 1.0e-9));
    assertThat(tile.getInterpolatedPoint(0, 0), geodeticPointCloseTo(v0, 1.0e-9));
    assertThat(tile.getInterpolatedPoint(1, 0), geodeticPointCloseTo(v1, 1.0e-9));
    assertThat(tile.getInterpolatedPoint(1, 1), geodeticPointCloseTo(v2, 1.0e-9));
    assertThat(tile.getInterpolatedPoint(0, 1), geodeticPointCloseTo(v3, 1.0e-9));
    Assert.assertEquals(0.5 * FastMath.PI, tile.getCenter().getLatitude(), 1.0e-9);
