From 66da2f537ae80ce2b31d1eaf34ad8c03d858938d Mon Sep 17 00:00:00 2001 From: Antonioya Date: Tue, 31 Jul 2018 10:22:19 +0200 Subject: New Grease Pencil object for 2D animation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit merge the full development done in greasepencil-object branch and include mainly the following features. - New grease pencil object. - New drawing engine. - New grease pencil modes Draw/Sculpt/Edit and Weight Paint. - New brushes for grease pencil. - New modifiers for grease pencil. - New shaders FX. - New material system (replace old palettes and colors). - Split of annotations (old grease pencil) and new grease pencil object. - UI adapted to blender 2.8. You can get more info here: https://code.blender.org/2017/12/drawing-2d-animation-in-blender-2-8/ https://code.blender.org/2018/07/grease-pencil-status-update/ This is the result of nearly two years of development and I want thanks firstly the other members of the grease pencil team: Daniel M. Lara, Matias Mendiola and Joshua Leung for their support, ideas and to keep working in the project all the time, without them this project had been impossible. Also, I want thanks other Blender developers for their help, advices and to be there always to help me, and specially to Clément Foucault, Dalai Felinto, Pablo Vázquez and Campbell Barton. --- source/blender/editors/gpencil/gpencil_intern.h | 271 +++++++++++++++++++----- 1 file changed, 216 insertions(+), 55 deletions(-) (limited to 'source/blender/editors/gpencil/gpencil_intern.h') diff --git a/source/blender/editors/gpencil/gpencil_intern.h b/source/blender/editors/gpencil/gpencil_intern.h index 90ff1e0bb25..0218530be4e 100644 --- a/source/blender/editors/gpencil/gpencil_intern.h +++ b/source/blender/editors/gpencil/gpencil_intern.h @@ -34,24 +34,144 @@ #include "DNA_vec_types.h" +#include "ED_numinput.h" + /* internal exports only */ struct bGPdata;
