Object drawing

Click the  icon in the toolbar to bring up the Object Drawing dialog box. The iEarth WebApp supports draw lines, draw surfaces, vignettes, geometries, and particles.

Draw Line

You can choose space mode, ground mode, SM mode, ground object mode, and support adding solid line, dotted line, outline line, arrow line, halo line, and inter-tail line.

Operation: Click the line you want to draw in the Symbol Library, set the attributes of the corresponding line, such as line color, line width (pixels), click "Draw", and then click the starting point of the drawn line in the scene, move the mouse to click the folding point and the end point of the drawn line, and then click the right mouse button to end the drawing.

Drawing mode can be selected from space mode, ground mode, SM mode, and ground-on-object mode, and supports the use of solid color, grid, and stripe face fill symbols to create face elements.

Operation: Click the face fill type you want to use in the symbol library, set the corresponding attributes of the corresponding fill type, such as the face color, click "Draw", then click the starting point of the drawn face in the scene, move the mouse to click the middle point and the end point of the drawn face, and click the right mouse button to end the drawing.

Vignettes

Symbol types can be selected from trees, public facilities, and transportation, and support adding chairs, garbage bins, newspaper kiosks, post office boxes, speed limit signs, street lights, traffic lights, trees, and other total 17 kinds of 3D point elements.

Trees support three modes of adding: single add, add along the line, add area.

• Single add: each mouse click will plant a tree at the mouse click, and you can click multiple times to realize continuous tree planting.
• Along the line to add: mouse click on two points to draw a line, along the line of the same type of trees can be planted evenly.
• Add area: draw a polygonal area in the scene, you can check the symbol for multiple selection, and randomly plant multiple types of trees in the drawn area. You can quickly and easily beautify a large area of the scene.

Operation: Click the vignette you want to draw in the symbol library, set the attributes of the corresponding vignette, such as symbol color, adding mode, deleting mode, click "Draw", and then click in the scene at the selected location, the scene will be loaded to display the added vignette.

Geometry

Support to add four types of geometry: Cylinder, Cube, Sphere and Cone.

Operation: Click the geometry you want to draw in the symbol library, set the attributes of the corresponding geometry, such as the length of the cone, the bottom elevation, the color, the drawing mode, click "Draw", and then click in the scene at the selected location, the scene will be loaded to display the added geometry.

Particle

Support to add three types of particles: flame, water droplet and firework, of which flame and water droplet support parameter setting and firework is a fixed effect.

• Flame: can be adjusted through the parameters to simulate a different degree of fire, torch effect.
• Water droplets: can be adjusted through the parameters to simulate the burst pipe, water column, fountain effect.
• Fireworks: left mouse button click anywhere in the scene to add fireworks effects.

Operation: Click the particle you want to draw in the symbol library, choose whether to parameterize, click "Add", and then click in the selected location of the scene, the scene will be loaded to display the added particles.
