Geocameras and Rendering

Use this sub-skill when a task needs BlenderGIS camera workflows: placing cameras, empties, or the 3D cursor from geotagged photos; switching a geophoto camera with its background image; or creating an orthographic map-render camera with a world-file text block.

Route First

• Scene CRS/origin setup, CRS validation, and reprojection engine choices belong to georeferencing-and-crs.
• Raster import, georeferenced images, DEMs, and basemap tiles belong to raster-dem-and-basemaps.
• Add-on enablement and cross-cutting dependency issues belong to the root add-on overview and root troubleshooting.

Use These Files

• references/workflows.md: end-to-end geophoto and georender procedures, validation, and world-file computations.
• references/operator-reference.md: operator IDs, options, side effects, custom properties, and exact world-file equation.
• references/troubleshooting.md: recovery steps for georef, GPS, format, context, selection, and pixel-size failures.
• scripts/read_exif_gps.py: standalone preflight helper for JPEG/TIFF photo sets before running Blender operators.

Core Operator Map

Workflow	Operator ID	Use when
Geotagged photo placement	camera.geophotos	Create target cameras, cameras, empties, or move the cursor from EXIF GPS photos.
Switch geophoto view	camera.geophotos_setactive	Make a BlenderGIS geophoto camera active and show its photo as the camera background.
Georeferenced render camera	camera.georender	Create or update an orthographic top-view camera over a selected mesh and generate a world-file text block.

Required Preconditions

• BlenderGIS is enabled and its camera module is available from GIS > Camera.
• The scene must be georeferenced (GeoScene.isGeoref true): valid CRS plus projected origin coordinates.
• Geophoto inputs must be JPEG or TIFF files with EXIF GPSLatitude, GPSLatitudeRef, GPSLongitude, and GPSLongitudeRef tags.
• camera.geophotos_setactive must run from a 3D View context.
• camera.georender must run in Object Mode with either exactly one selected mesh, or one selected mesh plus one BlenderGIS georender camera carrying the mapRes custom property.

Expected Success Signals

• Geophotos create objects at projected photo coordinates minus the scene projected origin. Cameras get camera-data custom properties background, imageWidth, imageHeight, and orientation.
• Switching a geophoto sets scene.camera, render resolution, and a visible camera background image for the selected geophoto.
• Georender creates or updates an orthographic camera, sets render resolution from mesh extent and target_res, stores mapRes, and writes a <camera name>.wld text block in Blender containing six world-file lines.
